The History Of Mark Grenon, A Pioneer Of Chlorine Dioxide Therapy

Mark Grenon treated people across the world for over 10 years until early in Covid when the FDA had him and his sons imprisoned in Colombia and then extradited to the U.S. Here I tell his story.

I will start by saying that most in the chlorine dioxide world I now inhabit consider Mark Grenon the most clinically experienced living practitioner of orally ingested (and/or bath administered) chlorine dioxide therapy.

Along with my Leading Edge Clinic practice partner Scott Marsland, I had a long Zoom conversation with Mark Grenon a couple of months ago, shortly after I started my research into chlorine dioxide. I'm sharing a paraphrased summary of the conversation transcript I made from the recording of that call with Mr. Grenon, along with details taken from other histories of his work with chlorine dioxide.

HISTORY OF CHLORINE DIOXIDE PIONEER MARK GRENON

Mark Grenon spent most of his adult life as a missionary pilot who ferried missionaries all over the Caribbean (and other places) for 46 years. From Dr. Robert Yoho’s Substack on Grenon:

Mark and his sons had built a compound in Barahona, Dominican Republic, to house US medical missions. Over the years, the teams performed surgical procedures and other assistance in local hospitals. One of Mark’s three oldest sons’ roles was to go to mountain villages to "triage” or examine those who needed surgery before they were transported.

During this time, Mark and his eight sons developed boils and abscesses on their legs, armpits, face, and body that were diagnosed as methicillin-resistant Staph Aureus (MRSA) infections. Mark was told by a few of the surgeons that no antibiotic available would cure them. One claimed that only amputation and skin grafts would help. Mark was a sophisticated healthcare provider, so he sought second opinions online. He eventually found Humble’s work describing MMS.

Mark thought it sounded like "snake oil,” but his sons’ infections were worsening and spreading among other children. He searched for other cures, but no pharmaceutical drug was promising.

After self-treating his whole family with MMS, all recovered. Mark recalls trying to educate the doctors that he was working with about his treatment success:

“So when I found out that MMS was curing my MRSA, these doctors are like, no, man, that's not going to be. You can't cure it. I said, You saw it on my body. You saw it on my son's bodies. It's gone. Anyways, the doctors stepped away. I know they stepped away because they would have lost their license if they got involved with what I was doing.

His life transformed, he began treating everything and anything with consistent, shockingly positive results.

He recalls writing to Jim Humble and saying:

I was doing it for three years without him (Humble). I wrote him and said, Jim, this stuff is fantastic. That is precisely what you've been saying, but I am dealing with the same things in a different culture and part of the world. This is a human study, Jim, what we're now doing. I have been doing it all over Haiti and the Dominican Republic. I'm using your protocols, which were very strong back then. And we're getting consistent results with a standardized protocol. So basically, we're doing a human study. So I wrote him. He goes, thanks, keep in touch. I was curing elephantiasis, dengue, AIDS, cancer, diabetes, and all kinds of stuff. So I started telling the doctors, but I lost all my supporters. They just said we don't want to have anything to do with you. You're crazy. FDA says it's poison. I'm like, look, this is what I'm doing!

We were around the world from 2010 to 2020. I did 63 seminars in 20 countries. We had scientists, doctors, and chemists coming to us. What I like about it is that it’s such a broad-spectrum, cheap, and easy. I wanted to keep it. Initially, I had a few guys who wanted to make a lot of money on it. I said, no, I don’t want to do that. I wanted the ordinary people to make it in their house. Honestly, I've had airplanes and mansions. I'm not interested in that stuff at all. I'm not. And I'm not trying to be pious. Money is just a tool to me. It's not something I live for. So, I just started trying to make it easy for everyone. Jim came and lived with us for three years. Jim and I developed these protocols. Honestly, though, he deserves all the credit.

THE UGANDAN RED CROSS MALARIA STUDY

Here, Mark tells the story of his involvement with the Ugandan Red Cross study of MMS, in which they rapidly cured 154 malaria patients.

If you think that's outrageous, it gets even better. There is a leaked documentary on YouTube (ED: since taken down, now on BitChute) that the Red Cross and the big pharmaceutical corporations do not want you to see. It happened in December 2012 in Uganda. People at the lower levels of the Red Cross, lower levels of command, heard about what Jim Humble was doing. These people believe the Red Cross is doing what it claims to be: helping people and trying to cure diseases. They went out there and said, why don't we give it en masse to see if it works in people with malaria?

The Ugandan Red Cross went in there and identified 154 patients who were positive for malaria. They gave all of them MMS under controlled circumstances. We did a little blood test, just a little prick, and then a quick strip malaria test. We identified 154 malaria-positive patients, together with the local health authorities and the doctors. All of them were treated. All of them were cured symptomatically between 24 hours and 48 hours with malaria tests that were negative and without any side effects. Days later, they were negative for any parasites.

I was excited because of the instant results among all the people we had so far tested. It was unbelievable that somebody who tested positive for malaria yesterday turned out to be negative today and feels significantly better, happier, and healthier. And what's sad is that after word got up to the higher levels of command of the Red Cross about what we did, they suppressed the whole thing. They now say it never happened; nobody was ever there. They even went as far as telling people that it was a hoax and it was a joke. The people who were there in the Red Cross shirts were just there for fun. They put the shirts on to put the whole thing together! I mean, it's just ridiculous. Ridiculous. Even the narrator of the film, an ex-veteran of the Belgian Army and ex-director of one of the Virgin Airlines, now says it never happened. I was never even there. That's how far they're willing to go to suppress the evidence.

THE FORMATION OF THE GENESIS II CHURCH OF HEALTH AND HEALING

As missionary pilots, we started the seminars when Jim came from Africa. Before we started the workshops, he had an idea about a mission, a church, or something. When he came to me, I was already doing that. I said, yeah, let's start a church because many people understand that the medical system is under these laws, statutes, and codes to protect their monopoly of the medical group and the pharmaceuticals. But a church isn't in that box. The church is under no law. That's why you can go to a church and get political asylum. A priest can give alcohol to a minor kid in public and not get arrested. You don't see priests in court because it's different. There's a box that “they” own, but the church is different. It is under natural law, whatever you want to call it, but we're entirely out of their box. We started the non-religious church, Genesis 2 Church of Health and Healing. We didn't want to be religious at all because I wanted a Muslim to come and learn how to take care of his family.

I wanted an atheist to be able to come so I could take care of his little girl or boy with leukemia. I want him to see his grandkid born one day. I want anybody to come. It has nothing to do with religion. This is the first church in the world that lets anybody come.

Mark went on to explain that they viewed, and wanted MMS to be viewed, as a “sacrament” of the church, which would “take care of our temple” (i.e., our bodies) and is “our God-given right.” He describes what happened during an early service of their new church:

“Well, they kicked in the door, and I immediately told them they had just broken into a religious service. 'We're having a church service here,' I said. 'This is a capital crime you are committing. Wars have been started from this kind of stuff.' But I felt like those people that do that are just puppets. They've been sent there. We asked the police to have them leave, and they did. I said, 'Come back when I'm done because I want to explain what we're doing and why we started the church. You will be interested in health if you have sick kids or don’t know. I want to tell you why we're doing it and why we won't listen to you. That's why we can say heal. We could say treat.'

But I'm not against the government. I wasn't against those people that came to me. They are just workers; they're trying to make a living. I'm against who sent them what their objectives and goals are to stop us and why. We're not letting it happen as a church. Five years since we started this church, we're in 115 countries. We have almost 1,800 health ministers, as we call them, who are trained to do all the protocols. We've got over 180 churches throughout the world in five years. In another five years, I hope we cover the whole world—a grassroots movement to show people how to control their health quickly and inexpensively. If MMS is as dangerous as they say it is, this poison that’s killing everybody, according to the FDA, then where are all the dead bodies?

There are none. There hasn't been a single death from the proper use of MMS, as instructed, since '96, when Jim Humble first discovered it as an effective cure for malaria. Where is all the negative feedback? Where is that? If you dig online into all the forums, YouTube posts, comments, and Facebook, you see that most of the feedback is positive, and the worst is just neutral. People are saying, 'It didn't taste so good, but I don't have hepatitis anymore.' People are carrying this stuff all over the world. It's a mystery that it still hasn’t exploded, but I think that's about to happen.”

Enter Kacper Postawski and Jeff, “The Curious Outlier.”

My new friends Kacper and Jeff played crucial roles in spreading the knowledge gained by Humble and Grenon to help preserve and restore human health worldwide. Kacper’s documentary “Quantum Leap,” released in 2016, was the first to go viral. Jeff's interest in chlorine dioxide was sparked when he first watched "Quantum Leap." This inspiration led him to conduct in-depth research on chlorine dioxide. Within a few years, he was motivated to self-fund and create the documentary and website “The Universal Antidote” in 2021 during COVID-19. I have an upcoming post about my interviews with each of them. The below is again taken from Robert Yoho’s history of Grenon.

Mark asked an Internet personality (Ed: Kacper Postawski) to help him produce a chlorine dioxide documentary. Initially published in 2016 at www.quantumleap.is with subtitles in nine languages, it was taken down during the "pandemic” in 2020. It is now available at THIS Rumble link.

Thousands of people worldwide watched it, enabling the “G2Church" to spread to more than 130 countries. Mark and his sons trained over 2000 people to use CD to treat many illnesses.

Another man who saw Quantum Leap was so impressed that he devoted over a year and more than $100,000 to producing a second complete documentary. By this time, Mark’s team had recorded thousands of CD testimonials, which he made available for the film. Since NASA had said CD was “the universal antidote,” TheUniversalAntidote.com was used for the movie’s web address. These two videos are required for viewing by anyone who wants to understand chlorine dioxide fully.

ASSASSINATION ATTEMPTS

Mark told me that even before Covid and his imprisonment at the behest of the FDA (Ed: you will learn more about that below), there were two assassination attempts on his life. He claims the first was by “CIA-type” people.

The CIA followed us in Arkansas in 2017 when I attended a seminar. It was a black suburban. I say CIA, CIA-type people. A black suburban stayed about six car lengths back on our right side. We were going down the highway. The place was quiet when we crossed from Memphis into Arkansas and got through the traffic. We suddenly heard, “BOOM,” And I'm like, what? I looked back. John, my son, was driving. Did you hit anything? No. We pulled over. Well, before we pulled over, that Suburban took off. We got hit, and they took off. It was all black windows, too. And we pulled over, and the tire fell off. If that had happened while we were going seventy, we would have flipped. We looked underneath our car, and the tie rod was melted. They stayed that close because they had a remote control with a thermite detonator that would melt steel. It melted it. I have a Land Cruiser with these giant tie-rod heads. It melted it. So they tried to kill me there.

I then asked him about the other assassination attempt. He continued:

They first tried to poison me in Mexico in 2014. I had a graduation in a restaurant for a seminar we did in Puerto Vallarta. Everybody had a bunch of chlorine dioxide. I know the person who did it because I healed her and her husband. We cured her hepatitis B, and we cured her husband of herpes. While I'm talking to him, we're talking as good friends. It turns out he was a Russian spy, and she's from Ukraine, and they are used to poisoning people, but I didn’t know that at the time.

There was a margarita or something on the table. I just took one little sip, waiting for my lobster and steak. Then I went to wash my hands. When I came back, the drinks had changed. I was like, hey, why did you change my drink? I didn't touch it, so I drank from the other.

And I was thirsty, so I took a big drink. I'm like, that's weird. Suddenly, within five minutes, I took a bite of my lobster, and it was like I had fallen out of my chair onto Kerry Rivera's chair, paralyzed. I'm on the ground; everybody's flipping out, saying, “Are you okay? You okay?” I'm looking right at that woman, and she's laughing. I was paralyzed within five minutes. On the ground, paralyzed, couldn't talk. I could feel it coming through my body to where I was having trouble breathing.

You bastard, you poisoned me, I thought. And I couldn't talk. I couldn't say anything. So they picked me up. Jim said that by the time they picked me up and put me against the wall, I was all white. He said you looked like you were dying right there. And I'm like, I couldn't talk. I couldn't do anything. I'm paralyzed. And then I snapped out of it after they poured chlorine dioxide down my throat.

After about five minutes of pouring it down my throat, I just puked. I puked up this green stuff. It looked like Prestone antifreeze. So anyway, I kept taking it. Two hours later, I urinated the same color, and I was better. Slept great. The following day, I got up fine.

After the assassination attempt in the Suburban in 2017, Mark published his first book around the same time Jim Humble finished his second. The most recent version of Mark’s book is here, and he covers many topics affecting our health besides MMS. One of my favorite sections is where he focuses on health propaganda and disinformation (which I now draw from when I need references to various chicanery “they” pull in trying to convince the population of health lies).

Mark recalls:

We worked on that one together while he lived in the Dominican Republic. We did 19 seminars there. In the first one, 45 people from 15 countries came because Jim had a pretty good-sized mailing list from his book sales. Nearly everyone who came had a testimonial of recovery from an illness. We ended up doing 19 seminars there.

But at the end of the second seminar, I heard a knock on my door. I had big compound gates. I opened them, and it was some men from the Consumer Protection Agency (I can’t remember what they call it in Spanish). They asked me if I had MMS. Could you please let me know why you're asking me that? We heard you have something called MMS that you are making available to people, so we are here to search your place. I said, Wait, first of all, we're a church. I've been here 10 years. They said you are a church? Really? At that time, I pulled back, and I got away.

He then talked about their books:

Mine is different than Jim's. Jim's first book was good but too strong. That's when I learned how to make it myself, and wow, we have a more straightforward formula. Then, when he was writing his second one, he was living with me. We'd go through all the chapters, and I would correct and revise a lot of the information in it because I was getting and learning from testimonies from around the world. And, Jim, add this, do this. So I wrote that book with him but didn't take credit.

Although not nearly as threatening or alarming as the above assassination attempts, lesser but persistent persecutions of the Genesis II Church, Humble, and the Grenons occurred across the world but particularly within countries that makeup what is called “The Five Eyes.” From Perplexity AI:

The "Five Eyes" refers to an intelligence alliance comprising five Anglophone countries: Australia, Canada, New Zealand, the United Kingdom, and the United States. It originated from the UKUSA Agreement, established after World War II. The alliance is considered one of the most integrated and enduring intelligence-sharing arrangements globally.

The Five Eyes countries collaborate closely to gather, analyze, and share intelligence on national security threats and global concerns. Their activities have expanded to include monitoring communications worldwide and addressing cyberattacks, terrorism, and regional conflicts. The alliance operates under high levels of trust, with member nations sharing intelligence by default while maintaining the option to act independently.

Actions such as being refused entry into Australia and New Zealand and media hit pieces aired against them while in Canada (after they tried to deny him entry but relented after Mark threatened to make their actions public). An example of a “mini-persecution” was when UK “Trading Agents” kicked in the door of a house in London where they held a service. Mark then called the UK police, which led to Mark's entertaining, informative, and successful defense when the cops started asking him probing questions about his church and the “sacrament” they were teaching about and giving away. Check it out; I clipped it to 24 minutes in length (the link to the full video for sharing is here):

The Covid Pandemic

In late 2019, the church launched an exciting broadcast called G2 Voice, just as reports of a concerning “bad flu” emerged. Mark eagerly sought out stories from those affected. By early January 2020, even before the official declaration of a pandemic, he was invited to share insights on the Alex Jones show (link to the show is here):

I went on with Bob Sisson and Alan Keyes. They just came back from Uganda. They had been doing MMS for 10 to 15 years over there, treating malaria. And they came back. Keyes said they were “getting negatives under the microscope in two hours in Uganda for malaria.” I'm on there with them, Alan Keyes, the guy that ran for President.

They're telling me what's happening over there, and we started using the word "cure." We were asked not to use the word cure, but it kept slipping out. We healed. It's just natural. I don't like that they can take a word out of the vocabulary and tell you you can't use it.

So after two years, remember, we had no victims at all. We had no one harmed or viable claims against us to say we hurt anybody. It was just the pharmaceutical companies. Pfizer called the FDA and told the FDA to shut them down through the quack watch in 2020 that Fauci and Dr. Birx had set up. They just put us on the list. If anybody is saying they're curing COVID, cease, or we're going to come after you, put injunctions on you.

On April 8, 2020, the FDA sent Grenon a letter informing him that “based on our review, MMS is an unapproved new drug” and that importing, selling, branding, or claiming it as a cure violates specific sections of the Federal Food, Drug, and Commerce Act.

Interestingly, I did not know the FDA classified chlorine dioxide as “an unapproved new drug.” I had been under the impression that the FDA’s official position was that it was a dangerous bleach-like substance that should never be ingested. However, later in the letter, they do not say consuming or treating someone with it is illegal. Still, instead, just like with my friend “the horse paste medicine,” the FDA “is advising consumers not to purchase or use certain products that have not been approved, cleared, or authorized by the FDA and that are being misleadingly represented as safe and/or effective for the treatment or prevention of COVID-19.”

THE ARRESTS, EXTRADITIONS, AND IMPRISONMENTS OF THE GRENONS

I will detail the facts of what happened next after I show you this mainstream news report below detailing (I mean propagandizing) the government’s actions and the Grenon’s supposed culpability. If you want to fully understand the deceit and dishonesty embedded in this “breaking news show,” I suggest you read either or both below posts, then watch the clip:

• The Existing Evidence Base For Chlorine Dioxide In Treating Human Diseases

• The Safety Of Orally Ingested Chlorine Dioxide At Commonly Used Treatment Doses

The reality about the above hit piece is that the Grenons and their church had been on a mission to help heal sick people worldwide for over ten years. They offered Humbles MMS by donation, which they called “sacramental products to detox our temple, the body.” For each $25 donation, they shipped two bottles of MMS, but if someone did not have the money, they gave it to them for free and paid for the shipping! Mark told me they made $1.2 million… over ten years. Split across five families, each family earned approximately $24,000 a year. Again, they were committed to healing, not hurting or profiting. So there’s that. In June 2020, they gave away all the MMS for free and sent 200 shipments a week until their arrest. They had stopped charging people. Wow.

Second, the government’s attack on them was absurdly excessive. Ten agencies executed the arrest and confiscation of their legally bought chemicals. Local sheriffs, local police, US Marshalls, FDA, DOJ, ATF, EPA (and others!). Helicopters circled above the house (you would have thought they were running a meth lab with this kind of police behavior). They arrested two of his sons and confiscated all their supplies, which had been purchased legally and for which they had all the receipts for their business. They even confiscated all copies of Mark’s book and never returned any chemicals or books. Further, they “tipped off the local news station” to prepare and air that hit piece above, which the authorities had also done when they were in LA doing a seminar.

Jonathan and Jordan Grenon were the ones arrested. Although some news reports stated that Mark and his other son Joe “fled to Colombia,” the reality is that they were already in Colombia and had been living there for 9 years at the time.

Mark and Joe had been doing podcasts in Colombia to spread the knowledge of MMS's efficacy. They did 204 two-hour podcasts on numerous illnesses, with hundreds of testimonies (his book contains testimonies on 40 different diseases). The link to all 200 podcasts is here.

Mark Grenon was then arrested in Colombia by Colombian authorities at the request of the United States. The arrest was coordinated through the U.S. Department of Justice (DOJ), specifically its Office of International Affairs (OIA), and involved collaboration with Colombian officials.

The U.S. wanted to extradite Mark and Joe from Colombia. Still, because they told Colombia that they were going to charge them with life sentences for “contempt of court,” Colombia refused (the extradition treaty between the U.S. and Colombia did not allow for extradition if the accused was to face a life sentence or the death penalty).

So, they dropped the contempt of court charges against Mark and Joe to extradite them to the U.S. for “conspiracy to defraud the United States.” They were both sentenced to 60 months, of which they served 49 months (over 4 years). Then, as per Mark, the judge took revenge on him by punishing his other sons, Jonathan and Jordan, by not only sentencing them for conspiracy to defraud but also for contempt of court. They received 151 months (12.5 years) and have served 56 months (almost 5 years already).

Although Mark related this account to me personally, I am instead excerpting the same account from an interview he did with Dr. Robert Yoho, who described it on his Substack “Surviving Healthcare.” In that post, he writes:

Grenon was arrested and imprisoned in Colombia for two years before being extradited to the US. Even while incarcerated in Colombia, he continued his mission, helping fellow inmates with health issues. He describes setting up "a table... 40 to 50 men every day coming by... doing the chlorine dioxide protocols." Support from wealthy inmates ensured his ability to continue his work even within the prison system.

In the Colombian prison.

Throughout our interview, Grenon articulated a sophisticated critique of the legal system that prosecuted him. He says that administrative courts lack constitutional authority, stating they are "an administrative judge in a corporation" who "don't have to give an oath or affirmation to uphold the Constitution because they don't use the Constitution." This understanding informed his legal strategy, although it did not prevent his conviction. Mark’s lawyer recently filed an appeal for his sons based on these issues because they are serving a longer term and are still in prison.

Please, readers, know that the Grenons are trying to fight and appeal these sentences but need your help. Below is a letter to Attorney General Pam Bondi asking her to review the case and to uphold the Grenon’s constitutional rights. A PDF version follows, and at the end of the post, I will include the plain text to copy/paste into a letter if that is easier:

FINAL APPEAL

Now, I have to say, if you have read all my posts on the persecutions and assassinations of oxidative therapy practitioners, here you have a chance to support ones that are still alive and who, in my opinion, have devoted their entire adult lives to helping humanity. Humanity should come to their defense in return. I myself just sent a donation to support their legal defense.

I will end with this appeal from Dr. Yoho on behalf of the Grenon’s:

Mark is now 67 years old and needs your help. His Social Security benefits were taken from him in Sept. of 2020. Grenon’s sons Jonathan and Jordan are still being held in federal prison. Please consider purchasing his books HERE (print version) and HERE (PDF download), and you can donate to the Grenons legal defense HERE. Since the FDA and DOJ silenced the Grenons, many people have died unnecessarily.

A wide-ranging discussion with attorney Todd Calendar describing the Grenons’ situation, the availability of chlorine dioxide, the commercial products, and much more is HERE.

LETTER TO PAM BONDI

{YOUR INFORMATION}

(Today’s date)

The Honorable Pam Bondi
U.S. Attorney General
U.S. Department of Justice
950 Pennsylvania Avenue NW
Washington, D.C. 20530-0001

Subject: Urgent Appeal for Justice – The Case of the Grenon Family

Dear Attorney General Bondi,

I am writing to you on behalf of Mark Grenon, Jonathan Grenon, Joseph Grenon, and Jordan Grenon, who have been unjustly imprisoned for nearly four years under deeply concerning circumstances. Their case presents serious constitutional issues regarding religious freedom, due process, and judicial overreach.

The recent appeal of Jonathan Grenon (Case No. 23-13478-GG) highlights multiple violations of constitutional rights, including:

• Violation of Religious Freedom – The prosecution failed to properly apply the Religious Freedom Restoration Act (RFRA) in assessing whether the government’s actions placed an undue burden on their religious beliefs and practices.

• Denial of Legal Representation – Jonathan Grenon initially represented himself but later requested legal counsel, which was denied, resulting in a miscarriage of justice.

• Denial of a Speedy Trial – The Grenon family endured an excessive two-year delay before trial, violating their Sixth Amendment right to a fair and timely hearing.

• FDA Overreach & Unlawful Convictions – Their convictions were based on FDA regulatory definitions rather than established legal precedent, raising serious concerns about improper administrative overreach.

The Grenon family’s ongoing imprisonment is not just an attack on them, but a dangerous precedent for religious freedom and constitutional rights in America. Their continued detention raises urgent questions about government overreach and the suppression of faith-based practices.

I respectfully urge your office to review this case, ensure transparency, and take immediate action to uphold the constitutional rights of the Grenon family. Justice delayed is justice denied, and every moment of inaction further erodes the fundamental freedoms this nation was founded upon.

Thank you for your time and attention to this critical matter. I look forward to your prompt response and your commitment to defending religious liberty and due process in this country.

Sincere hope of God speed attention,

(your contact information)
