The Team Behind Your Transformation
Founded in 2011, Pro-Fit Health Performance Medicine combines functional medicine, precision diagnostics, and performance optimization to help clients reclaim their health from the inside out.
Root Cause Medicine, Not Band-Aid Solutions

Root Cause Focused
We dig deeper than symptoms to find and address the true source of dysfunction.
Data-Driven Decisions
Every protocol is backed by 20,000+ biomarkers of clinical data and precision diagnostics.
Whole-Person Care
We treat you as a complete person — mind, body, and performance — not just a set of labs.

Built From Personal Experience
Twelve years ago I was a single mom with nothing to fall back on, and my body was breaking down. PTSD. Autoimmune thyroid disease. Gut problems no one could explain. A metabolism that had flat quit on me. I did everything I was told. I saw the specialists, took the prescriptions, and still woke up feeling like a stranger in my own body. Every one of them looked at a single piece of me. Nobody looked at the whole thing.
So I stopped waiting for someone to fix me and learned how to do it myself. I certified as a Functional Diagnostic Nutrition Practitioner, then earned my Master’s in Functional Medicine and Clinical Nutrition. I’ve always been the type who reads everything and needs to know why, so I never stopped, course after course, deep into the research, and hands-on inside real practices to see how care actually happens: a longevity and HRT clinic, dermatology practices, and Lifetime. I read my own labs, adjusted, and slowly put myself back together. That’s where Pro-Fit came from: treat the whole person, find what’s actually driving the problem, and quit chasing one symptom at a time.
We still work that way. Real testing, real data, and a team that actually talks about your case instead of handing you off. We won’t sell you what you don’t need, and if we’re not the right fit, we’ll tell you and point you to someone who is. I built the care I couldn’t find back then. I’m glad you won’t have to look as hard as I did.
Your Whole Picture, Under One Roof
Most clinics hand you off. Your labs go one place, your hormones another, your nutrition somewhere else, and no one connects the dots. We don’t work that way. Since 2021 we’ve kept functional medicine and physician-led medical care under one roof, so your labs, hormones, peptides, nutrition, and training get read side by side by a team that actually talks to each other. Less guessing. Fewer dead ends. A plan built around your biology, not a template.
Lab Testing & Coaching
Your testing and coaching can happen anywhere in the world. We read your numbers and build a plan you can run from home.
Physician-Supervised HRT & Peptides
Hormone and peptide therapy, prescribed and monitored by our physician, in Alabama, Georgia, Texas, Florida, South Carolina, Kentucky, Virginia, and Illinois. More states are coming.
Same team, same care, whether you’re down the road or across the country.
