Assistant Professor of Medicine, Division of Gastroenterology and Hepatology

Clinical Contact


Dr. Barish joined the faculty in 2018 as Clinical Assistant Professor of Medicine in the Division of Gastroenterology and Hepatology after retiring from 33 years of practicing gastroenterology in Raleigh, NC. He is currently mentoring our GI fellows in their clinics and believes that there are two secrets to success as a physician: listening to patients and staying current with advances in medicine.

Clinical Focus

As a practicing gastroenterologist, he treated most GI disorders but had a particular interest in the diagnosis and management of inflammatory bowel disease. He has been active in clinical research since 1985 and has authored and co-authored numerous articles regarding GI diseases in various medical journals and books.


Dr. Barish is listed as a Top Doctor with US News and World Report, Castle Connolly, Becker’s GI & Endoscopy, Guide to Americas Top Physicians and American Registry’s Top 5% of “Most Honored Professionals”. He was also one of the first physicians recognized in the Bridges to Excellence IBD Care Recognition Program, sponsored by the American Gastroenterological Association’s Health Care Incentives Improvement Institute.
