Marshall Integrity
At Marshall Lifestyle Medicine, integrity is more than just an abstract value—it’s a measurable standard. We are built for high-performing men and women who demand excellence in every aspect of their lives, especially their health.
Our approach is rooted in data-driven decision-making, proactive surveillance, and executive optimization—because elite performance requires elite healthcare.
Why Results Matter
High achievers don’t leave success to chance. High achievers track, analyze, and refine in every aspect of their lives—because what gets measured gets mastered. Traditional healthcare often operates on vague recommendations and reactive treatments. At Marshall, we reject that model. Instead, we provide:
- Precision Health Metrics: Biomarkers, performance benchmarks, and predictive analytics to eliminate any potential guesswork.
- Goal-Oriented Blueprints: Customized strategies for longevity, health span, and peak performance.
- No-Excuses Accountability: A system that matches your discipline, ensuring compliance and results.
For our clients, failure is not an option—because success doesn’t happen by accident.

See What Our Members Have To Say:
Wil:
“I have been a client of Marshall Lifestyle Medicine for over 8 years. Dr. John Mullins is by far the most thorough, knowledgeable and caring doctor I have ever known. You know the "wait", then wait again in the "little waiting room" routine [of most traditional healthcare practices]. Then the doctor comes in and spends 3-5 minute. I have known Dr. Mullins to spend 30 minutes or more. He talks with you until he understands your concerns. As a concierge doctor, he is literally reachable 24-7. I have recommended him many times.”
Dan:
“I've been a member since early 2021, and it's been nothing but transformative. Paige and Dr. Mullins have helped me find the perfect balance of meds/supplements to support my overall well-being -- and outward appearance! Feel and look 10 years younger. I'd highly recommend Dr. Mullins' practice and his approach to well-being. It pays for itself 10 times over, and will make you feel like you've got an entire VIP team ready to support you on your healthcare journey.”
Marshall Lifestyle Medicine is designed for those who:
- Take ownership of their health like they do their careers.
- Demand data over guesswork, results over promises.
- See challenges as opportunities to optimize further.
