Please summarize your healing story in 100 words or less I was losing my battle with leukemia and lymphoma. I decided to become the first person swim the entire 184 mile length of the Willamette River as an active cancer patient to inspire other cancer patients to refuse to give up their dreams simply because they have received a diagnosis. Little did I know (or would have ever dared to imagine) that swimming 22 days in 40 degree water would have the power to heal my leukemia and put me into a radical remission.

I was diagnosed in a pre-surgery blood test when I was electing to have a total knee surgery in 2006.

Please tell us your healing story in as much detail as you would like:

I was not doing well. My numbers were going in the wrong direction. I had lost my wife 15 days before our 30th anniversary and was grieving the loss terribly. I was down to 159 lb.s (and I am 6'1"). I decided that I needed a purpose to give my whole heart to. I found an old journal that I kept as a 12 year old. It reminded me that I had always wanted to swim the English Channel. As crazy as it seems, that is the only thing that made me excited about living. So, against my doctor's advice, I got in a public pool on August 13, 2013 and started swimming. The first day, I was only able to do 11 laps. It took me over an hour! But...I felt alive. I felt like I had purpose again. By November, my numbers started going in the right direction, I was gaining weight and my head was starting to clear. I realized that if I put on a Speedo and swam to France, it did the world no good. I started asking prayerfully, how could I do this same challenge and make it about something bigger than me.

I soon found that the longest river in my home state of Oregon (the Willamette River) had not been swum. I decided to become the first person to swim its entire 184 mile length or die trying...literally.

This challenge gave my life meaning. To accomplish this, I would have do everything in my power to make my body and mind stronger. I cleaned up my diet, started juicing kale and granny smith apples, getting more sleep, and meditating at least once daily.

On June 3, 2014, I got in the Willamette River. I swam 3-5 marathons a day for 22 days (taking every Sunday off) and on June 27th I swam into the Columbia River to become the first person in history to swim the entire length of the Willamette.

I partnered with the Leukemia and Lymphoma Society to raise money and awareness for cancer research. My aim was to inspire other cancer patients to refuse to give up simply because they had a diagnosis.

After the swim, I knew I felt significantly better. When I went down to UCSD the next March, Dr. Castro was shocked to find that the CLL was gone. He said that he had never seen a radical remission of CLL in his 30 years as an oncologist and that if he had not done the blood tests himself, he would think I had been misdiagnosed.

My lymphoma didn't go away, however. I had read the research from Nippon University by Dr. Qing Li about "Shinrin Yoku" or "forest bathing." Before I would relent to chemo, I decided to run a 6 month experiment on myself. I started spending one full night every week in the Mt. Hood Wilderness with nothing buy a sleeping bag and a backpack hammock deep in the forest and about a mile off any trail. I began this routine in May of 2015 and by March of 2016 my lymphoma was gone. I have continued these practices and stayed cancer-free.

UPDATE: As of October 2020 Dean is thriving post-diagnosis.

I have a cold water immersion tank (Morozko Forge) in my garage that I keep at 40F. I get in it first thing every morning for 5 minutes and then after long workouts. The work of Wim Hof has found that routine exposure to freezing temps boost the immune system and metabolism as well as take down inflammation. I, also, spend at least one full day every week out deep in the wilderness with nothing more than my hammock and a good book. It's the most efficient reset/stress reliever I have ever found...and, as you know stress is a killer. am working with a filmmaker who has had a couple of documentaries on Netflix to capture my story. We hoped it would be out by next June, but due to the pandemic, plans keep getting pushed out. I have at least 3 more world-record extreme distance swims planned around the world that also depend on my ability to travel. I think the most important message I would like to highlight is that the "best way to fight cancer is to love life." None of us, (active patient, recovered, never been sick) know how many days we have. We must squeeze every day for what it's worth by living out our passions fully!

UPDATE: As of April 2022. Dean continues to thrive in health. I continue to be in near-perfect health with no evidence of any sort of cancer. Now, that COVID seems to be over, for the most part, I am free to continue to swim. I am making a bid to be the first person to swim the entire length of another river (and raising money for Beads of Courage org.). I will be swimming the 111-mile length of the Umpqua River in Oregon from June 13th to 24th.


1. I have fallen in love and married a wonderful woman who is a personal trainer, Bobbi ( She is as beautiful inside as she is on the outside.

2. We are beginning to offer retreats at destinations around the world and teach others how to "come back" from overwhelming loss, diagnoses, or any other of the difficult setbacks life can throw at you.

3. I remain cancer-free and thriving.

4. The biggest news- I have decided to earn my certificate as a Radical Remission Health Coach in this latest cohort and looking forward to becoming a more connected member of the radical remission community.


Dean is thriving, continuing to swim rivers around the world to inspire cancer patients, has added a certification as a Radical Remission Health Coach to his clinical practice as a therapist/coach and written his story in a book called "The Wild Cure: From Death to Life on Oregon's Longest River."

Do you have any thoughts about what may have caused your health challenge in particular, or what causes it in general?

I am a licensed therapist/coach who specializes in anxiety and trauma. For 3 years before I was diagnosed I saw mostly sexually traumatized clients more than 30 hours a week. I think I didn't have enough respect for how much second hand trauma I was constantly absorbing from hearing the worst stories of rape and molestation all day, every day. Also, while I always exercised, I didn't manage my diet well, slept little, worked too much and was chronically stressed out. Being from my generation, I was taught to repress my emotions and never display them. This led to chronic unresolved anger and fear.

After my wife died of brain cancer, the grief was too much. It took all of these weak areas and magnified them.

I believe that cancer has three main causes-

1. Poisoning- Some people are poisoned either through what they ingest or by environmental factors.

2. Unexpressed negative emotion/trauma- Many of us simply are not taught how important it is to feel and release our negative emotions. A chronic state of unexpressed emotions leads to constant tension in the body that suppresses the immune system until cancer has an optimal breeding ground for disease.

3. Disconnection from nature- We are so far removed from our natural habitat it causes a chronic state of dis-ease- Finding your way to connect routinely with nature has a powerful effect on the mind and body. I call it the "Wild Cure."
