Nobody Was Going to Outwork Me
Adopted as an only child, I grew up questioning who I was and where I belonged. I wasn’t the most gifted athlete, nor the most popular kid, but one thing defined me early on: “Nobody was going to outwork me.” That mindset became my foundation.
In elementary
school,
when asked what I wanted to be,
I proudly declared, “A professional baseball player.” The class laughed.
But my teacher pulled me aside, handed me a blank piece of paper, and said, “Write it down. Carry it with you.” I did and kept it for decades. Despite receiving only one scholarship offer, I walked on at Phillips University in Oklahoma, where a coach told me I’d never start. I didn’t argue. I worked, hitting until my hands bled, out-training everyone around me.
By senior year,
I earned a starting spot.
Still undrafted, I pursued my dream abroad, becoming one of the first Americans to play professionally in Australia, earning Rookie of the Year honors in 1989. One night, sitting in the dugout, I opened my wallet. Behind my driver’s license was that old, wrinkled note: “I will become a professional baseball player.” I cried. Because it had come true. Because hard work had made it real.
Later, I joined the Tulsa Police Department
and traveled globally with the renowned Power Team.
But it was in the crucible of SWAT raids and high-risk operations, busting down doors, facing life-or-death moments, that I saw something deeper unraveling.
Hypertension. Burnout. Prescription dependence. Marriages collapsing. Minds unraveling. I realized the greatest threat wasn’t outside the door; it was inside the system. So when I was tasked with developing a wellness program for the police academy, I went all in. I dug into the research and was devastated by what I found: the average police officer died just five years after retirement. I’d seen the signs, and I’d lived them. And it lit a fire I couldn’t put out.
I went on to become a traditional naturopathic doctor
certified in peptides and genetics, and began helping people break free from the systems that were slowly breaking them.
But if you ask me what drives me? It’s not the stats. Not the spotlight. It’s the memory of watching good men break under a system that promised to protect them. And the fire that still burns in me to make sure no one else has to go down that road alone.
Because once you’ve kicked down doors to save lives, you’ll do everything in your power to keep people from needing rescue at all.
A Mission Bigger
Than One Man
My mission became unstoppable when I met Michele. Together, we transformed a single clinic into the Functional Medical Institute, a nationally recognized hub for transformation serving patients worldwide, and became known as The Real Longevity Doctors TM. I bring the discipline of a SWAT leader and the precision of a naturopathic doctor, pairing tactical strategies with a relentless commitment to results.
We’ve co-authored seven books, produced eight feature-length health films, and created the signature “Night of Empowerment” experience that has equipped thousands to reclaim their health. Long before “biohacking” became a trend, I was already living it: testing, refining, and teaching systems designed to help people dominate their decades.
Because for me, health isn’t luck; it’s leadership. I know firsthand that nothing in life changes without effort, and I’m proof that hard work and relentless ownership can rewrite your story.
My mission is simple: to help you live younger, stronger, and longer — by choice, not chance.
Real People. Real Results.

Reversals.
If you’re looking for positive change in your health, I recommend Kingdom Fuel.
A complete meal replacement, or a boost for your workouts. I enjoy it, and hope you’ll give it a try!
I've enjoyed Kingdom Fuel all season, and highly recommend this healthy shake!
I have learned so much to improve my health journey from Dr. Mark and Dr. Michel and feel better than I have in years.
I was confused about what supplements I should be taking with so many different advertisements out there, but they were able to tell me exactly what my body needed after getting bloodwork results and I now have issues under control that I have dealt with for years. I highly recommend FMI to anyone who desires a Dr that cares about getting to the root of a problem rather than just getting prescribed medications with negative side affects.
I’ve been seeing FMI for years.
The entire office is professional and very nice that goes from the facility, the staff and of course the doctors. I would highly recommend FMI to anyone that is trying to maximize their health and live longer. This is not your typical doctors office that simply wants to give you a pill due to lab results. I feel very fortunate to have Mark and Michele expertise and experience in helping me optimize my health based on my individual needs. Thank you to your entire team!
Dr. Mark and Dr. Michele are very accommodating. Icing on the cake is I'm down 25 pounds and counting.
Friendly staff! The doctors are so patient and answer questions in very easy to understand explanations and are willing to discuss a variety of ways to get you and your body operating at peak performance! Never judgmental when you're stuck, just very helpful and encouraging! I love this place! We drive 2 hours for our in person visits when needed and zoom call the other.
Dr. Sherwood and staff take time to clearly explain everything affecting your health journey.
It can feel daunting when getting started, but everyone is intentional about making sure you understand and are comfortable with all aspects of their plan for helping you achieve optimal health.
Don’t just age well — dominate your decades.
