CLINICAL LEADERSHIP
Dr. Tony DeFrance, MD
FOUNDER, LEAD PHYSICIAN, CEO
TRIPLE BOARD-CERTIFIED
Interventional Cardiologist · Cardiac CT Angiography Specialist
American Board of Lifestyle Medicine · IFM Cardiometabolic Certified
Dr. DeFrance's clinical career spans more than two decades at the leading edge of cardiovascular medicine. As an interventional cardiologist, he performed complex cardiac procedures and trained thousands of physicians globally in advanced cardiac imaging techniques — developing rare expertise in how cardiometabolic disease presents across its full spectrum, from early imaging findings to acute intervention.
"The patients I was treating had the biology of this disease for years before they arrived. My practice now begins much earlier."
His transition into lifestyle and functional medicine was not a departure from cardiology — it was a logical extension of it. The biology driving cardiovascular disease, metabolic syndrome, type 2 diabetes, and cognitive decline is the same biology. Addressing it requires understanding it, and understanding it requires being willing to explain it clearly to patients — something the clinical visit alone rarely allows.
At MedMentor, all consultations are led personally by Dr. DeFrance. The goal is not to become a patient's ongoing physician — it is to provide the kind of informed, direct clinical perspective on cardiometabolic findings that helps people understand what they are looking at, what it means biologically, and what structured next steps are available to them.

Our Mission
To help people understand and act on the biology driving their health.
MedMentor exists to provide the education, structure, and implementation support that enables people to engage meaningfully with their cardiometabolic health — earlier in the process, when meaningful change is most achievable.
​
We believe that most people, given a clear biological explanation and a structured path forward, are capable of making changes that significantly alter their health trajectory.
"Extending not just lifespan, but healthspan — the years lived with energy, clarity, and function."
The People Behind the Program
Dr. DeFrance is supported by a team of specialists whose expertise spans behavioral change, functional nutrition, and lifestyle medicine — together providing the clinical depth and practical support that sustained cardiometabolic change requires.
