“Dr. Friedman and his staff at Prevent Medical provide an incredible lifestyle change program. During each session, Dr. Friedman provides valuable education on the weekly focus, with in-depth, supportive discussions. Dr. Friedman is deeply committed and never ends a meeting until all information is fully understood. The program beautifully encourages recipe sharing and creative movement ideas.

About Dr. Isaiah Friedman
I'm a physician board-certified in Radiation Oncology and in Lifestyle Medicine, a medical specialty that uses evidence-based behavioral interventions — nutrition, physical activity, sleep, stress management, and other daily habits — as the primary tools for preventing and treating chronic disease.
Through years of practicing oncology, I came to deeply appreciate how much lifestyle shapes health outcomes, often more than any single treatment. That conviction is what drives my work today.
I specialize in helping my patients make meaningful and lasting improvements to their health and sense of well being through evidence-based Lifestyle Medicine. My approach is thorough: I draw extensive laboratory work to understand exactly what's happening in your body, and I use that data alongside a detailed assessment of your habits and history to build a personalized plan.
Care is delivered via telehealth, so you can work with me from wherever is most convenient for you. I combine structured weekly sessions with close medical oversight — monitoring your labs, adjusting medications when appropriate, and staying in regular communication with your broader care team so that everything stays coordinated.
My goal isn't to replace your existing providers. It's to give you the focused, evidence-based support that most clinical settings don't have time to provide — and to help you take an active, informed role in your own health.

Dr. Friedman was clear and concise and didn’t waste my time and a pleasure to talk to. He gave the time to get to know me and my habits rather than just giving me the plan. Highly recommended!

Dr Friedman is hands down one of the best docs I have ever encountered. He is unusually dedicated and has been super accessible, always returning my calls and responding to messages promptly, and often spending extra time with me. He also listens to me carefully and, unlike others doctors in my experience, takes my concerns and symptoms seriously

Dr. Friedman is by far the best doctor I have ever had. He took extensive bloodwork that uncovered a medical condition I have that previous docs had missed, and his lifestyle program has dramatically improved my overall health, sense of wellbeing, and knowledge-base surrounding health, nutrition, and exercise. He is incredibly patient, dedicated, and knowledgeable and I feel lucky to have him as my doctor.
