About Me

"Commitment to skillful and compassionate practice of gastroenterology with emphasis on prevention is an integral part of my practice."

Ramin Zabihi, M.D. brings over 17 years of valuable experience in clinical gastroenterology and hepatology (the study of the liver and pancreas). His experience is coupled with extensive skills in a variety of endoscopic procedures - including ERCP (a procedure which evaluates the biliary system and pancreas). Dr Zabihi emphasizes preventive medicine and believes that current technology, together with physicians' dedication and patient education, could make colon cancer a disease of the past. He treats his patients as a whole individual, with paying attention to all aspects of their care.

Dr. Zabihi's Professional Qualifications include being Board certified in Gastroenterology, Hepatology and Internal Medicine. He is also a member of the American College of Gastroenterology and the American Gastrointestinal Association.

In 1992, he completed his residency and fellowship in gastroenterology at Loyola University in Chicago. Since then, he has been in clinical practice as an attending physician as well as serving as the chairman of the Department of Gastroenterology in Kaiser Permanente and Talbert Medical Group.
