Jeffrey Mark, MD

For functional gut health and digestive care in San Ramon, Jeffrey Mark, MD is here to help. We are a gastroenterology practice that combines traditional medicine with a functional approach, using testing, targeted supplements and lifestyle guidance rather than relying only on standard prescriptions.

Many of our patients have found that typical general practice care hasn't resolved their digestive concerns, and we take the time to look for the underlying causes. Our care is available through telehealth, which makes it easier for busy patients across San Ramon and the East Bay to receive a comprehensive, personalized care plan without a long trip.

We are known for listening closely, explaining the reasoning behind each test and recommendation, and providing clear follow-up on results. Patients who have been with us for years tell us they trust the care and attention they receive, and that continuity is something we value deeply.
