The Approach
Healthy is the baseline.
Optimal is the goal.
Know your numbers. All of them.
VO2 max, body composition, vascular health, continuous glucose, cardiac function, hormones — the data that actually predicts how you’ll age.
Tune the engine.
Hormones, mitochondria, metabolism, recovery, and sleep — optimized with precision protocols, not generic wellness advice.
Defend the gains.
Ongoing physician oversight that catches small drifts before they become diagnoses — proactive medicine, years ahead of the problem.
Advanced Diagnostics
If you don't measure it,
you're guessing.
A diagnostic suite most physicians have never had access to — under one roof, interpreted by physicians who know you.
VO2 Max Testing
The single strongest predictor of longevity — measured precisely, trained deliberately.
InBody 270® Composition
What the scale can’t tell you: where your weight actually lives, and how it’s trending.
Defend the gains.
See exactly how your body handles food, stress, sleep, and training — in real time.
GlycoCheck® Vascular Assessment
The health of your smallest blood vessels — where cardiovascular aging shows up first.
Multi-Function Cardiogram
A deeper look at heart performance than a standard EKG was ever designed to give.
FibroScan® Liver Assessment
Quantified liver health in minutes — no needles, no guesswork, no waiting for symptoms.
Brain Gauge® Neuro Assessment
Objective brain-performance tracking — focus, processing, and recovery, measured over time.
Precision Lab Panels
Hormones, inflammation, nutrients, metabolic markers — far beyond the annual-physical basics.
Hormone Optimization
Bioidentical optimization dosed to your labs and goals — energy, recovery, body composition, drive.
The Long Game
Your trajectory matters more than any single number.
Anyone can run labs once. The power is in the trendline: a physician who knows your baseline, watches your data year over year, and intervenes the moment something drifts — a decade before it would have become a diagnosis.
- Annual deep-dive assessment against your personal baseline
- Quarterly tracking of the markers that matter most for you
- Direct physician access when life throws a curveball
- A plan that evolves with your training, your work, and your age
Ongoing Care
Optimization isn't an appointment.
It's a relationship.
Proactive, not reactive
Scheduled assessments and check-ins designed to stay ahead of problems — not respond to them.
Direct physician access
Questions answered by the doctor who knows your data — not a portal, not a stranger, not a two-week wait.
A team that knows your name
The same physicians, year after year, invested in your long-term trajectory — medicine the way it used to feel.
Membership built around your goals
From annual deep-dives to full ongoing optimization — we'll match the level of care to where you are and where you're headed.

EXCELLENT Based on 59 reviews Posted on Google Jennifer LymanTrustindex verifies that the original source of the review is Google. In addition to being incredibly knowledgable, I really appreciate the care Kate takes with her patients. It's very valuable to me that they are functional medicine physicians/NPs at this practice vs those who wear the doctor title without having medical training.Posted on Google Joanne CurranTrustindex verifies that the original source of the review is Google. NPs Justina Timms and Sarah Taylor are always incredibly well prepared, knowledgeable and take all the time needed to explain labs and test results to me in ways that I can understand. Their professionalism and expertise continue to astound me. They also check in after procedures or explanations with well documented follow up. In addition, every nurse at the clinic is warm, friendly, personable, knowledgeable and professional to the Nth degree! Theresa, Michelle, Whitney, Lauren, Brenda, Mary and Chelsea all work hard and are extremely timely when completing procedures such as HBOT and MDI treatments. I have nothing but the highest regard for the James Clinic and all who work there including their lead Dr. Mollie James. My gratitude runs deep for their services.Posted on Google Mark YorkTrustindex verifies that the original source of the review is Google. Cutting edge technology. Highly trained and professional staff who love to serve. They are FRIENDLY too! Cured my cancer and making great progress on diabetes. The only way you can go wrong is to not give these folks a shot!Posted on Google Stephen NewlonTrustindex verifies that the original source of the review is Google. I used to be super active — then COVID hit, and everything fell apart. I felt blindsided. My life shrank to the floor, and walking to the kitchen became a challenge. I had health insurance, but no real care. After searching online, I found Dr. James. She offered something I desperately needed: hope — and just as importantly, genuine understanding. We tried different approaches, I improved a little, and I began to accept that this might just be my new normal. But Dr. James didn't give up. She researched, consulted colleagues, and kept pushing. No doctor had ever invested that much effort in helping me. Then one day, she mentioned MDI. I was skeptical, but willing to try. Eight sessions later, I have my life back. That's not an overstatement — imagine going from barely existing to truly living again. The road to recovery isn't easy, especially given everything we're up against today. But I'm back, and it's because of Dr. James.Posted on Google Susan FosterTrustindex verifies that the original source of the review is Google. Dr. james and the entire staff show such compassion and genuinely care for their patients. We are so thankful for the time they spend on our treatment plans, as well as the knowledge they have. Always give us hope. Blessed to have them as part of our medical team!!!Posted on Google Michelle HarrellTrustindex verifies that the original source of the review is Google. I love being able to go to the James Clinic and they have been a blessing to me over the last 3 years. Everyone there really listens to you and is always respectful. This is how medicine should be and is hopefully changing the status quo going forward. They are very interested in getting to the root cause of your symptoms and offering outside of the box treatments that I would never have been offered from conventional medicine.Posted on Google Jessica OTrustindex verifies that the original source of the review is Google. When I was diagnosed with cancer summer of 2025, my sister found out about the James Clinic. I called and got myself set up and they were so helpful! Whenever I have had a question or issue with anything Dr. James and her staff respond back quickly which is very much appreciated! I have been getting hbot and IV therapy for 7 months now. The past 3.5 months I have been going through conventional treatment and I repeatedly get told by the oncologist on how well I am doing. Also, a big shout out to the clinic IV nurses they have been fantastic! I am so very thankful to have the James Clinic supporting me through this diagnosis.Posted on Google Angela NorrisTrustindex verifies that the original source of the review is Google. The James Clinic team is phenomenal! After searching for years for a physician to assist me in getting to the root of my underlying condition, I finally found Sarah at James Clinic. Their clinic approach is whole person and patient centered which allows for individualized care. It is very empowering because you are heard and part of the healing process.Posted on Google Melissa IahnTrustindex verifies that the original source of the review is Google. I cannot praise Dr. James and her incredible staff enough! This is the only practice that has truly listened to my concerns, truthfully considered treatments/benefits/risks, and honored my personal health goals all while considering my lifestyle preferences when treating my health. I am grateful to have such a supportive and encouraging doctor who truly cares about my wellness! Everyone should have a doctor as caring as Dr. James to help them make the most important choices about their health!
