About Us

Practitioners that put you first, every time

We did not build this practice to manage chronic disease. We built it to reverse it. That distinction shapes every clinical decision we make.

About Us
The Way We Listen

Backed by 20 years of clinical experience.

Our standard is optimal, not normal.

Most clinical appointments last seven minutes. Ours do not. Before we order a single test or make a single recommendation, we sit with you and take the full history – symptoms, timeline, medications, lifestyle, failed treatments, and what you actually want your health to look like. That conversation is not a formality, it is the most important diagnostic tool we have.

Functional Medical Institute Story

Dr. Mark Sherwood

The Physician Who Learned What Stress Does to the Body From the Inside Out

Before Dr. Mark Sherwood became a naturopathic physician, he spent 24 years with the Tulsa Police Department, the final decade as a trained SWAT sniper. He watched elite men deteriorate in their forties. Operators who had been physically exceptional at 30 were overweight, medicated, and metabolically broken at 47. Chronic cortisol elevation, unaddressed hormonal decline, poor sleep architecture, inflammation, and nutrition - his body had ever connected these dots for them. Nobody had given them the right protocol in time.

Dr. Michele Sherwood

The Physician Who Knows What a Body Performing at Its Peak Actually Feels Like

Dr. Michele L. Neil-Sherwood is a Doctor of Osteopathy, Fellow in Osteopathic Internal Medicine, and iFM Certified Practitioner. She is also a former national physique champion, a taekwondo black belt, and a judo black belt. Every clinical decision she makes is informed by what she knows from lived elite performance requires, what hormonal and metabolic breakdown looks like as it develops, and what a full reversal actually involves.

Their combined clinical perspective:

Naturopathic precision and osteopathic depth produces a diagnostic picture that neither discipline produces alone.

By addressing the physiological, hormonal, genetic, and lifestyle dimensions of every patient's presentation simultaneously, they consistently deliver outcomes that isolated specialties cannot.
