Overview
Dr. Mark M. Tsuchiyose is a board-certified gastroenterologist with over 35 years of experience in the diagnosis and treatment of gastrointestinal and liver disorders. He provides personalized, patient-centered care and is highly skilled in diagnostic and therapeutic endoscopy to achieve the best possible outcomes.

At the Center for Diabetes and Cardiometabolic Health (CDCH), Dr. Tsuchiyose has successfully improved liver health, reducing liver fat in approximately 90% of patients through metabolic and nutritional interventions. He is also a committed advocate for physician support, community health, and public wellness.
