About me

Board-certified in gastroenterology and internal medicine, James H. Lewis, MD, has spent more than 30 years treating all forms of chronic and acute liver disease as a sub-specialty in the Washington, D.C., area. Dr. Lewis is Professor of Medicine at Georgetown University School of Medicine, and Director of Hepatology in the Division of Gastroenterology. He currently serves as Associate Director of the Gastroenterology Fellowship training program of the combined MedStar Georgetown University Hospital, MedStar Washington Hospital Center and the DC Veteran's Affairs Medical Center.

A recognized local and national expert on the management of hepatitis B, hepatitis C and drug induced liver disease, Dr. Lewis is widely published in the profession's most prestigious clinical journals. He also serves as a reviewer for multiple journals and on editorial boards. The author of several books and numerous book chapters, Dr. Lewis is a frequent lecturer at the regional and national level.

In addition to direct patient care, Dr. Lewis has extensive consulting experience with the FDA and pharmaceutical manufacturers on a variety of liver-related conditions. His special research interests include viral hepatitis and drug induced liver injury. Dr. Lewis is committed to his patients and often cares for those dealing with very complex liver conditions, including acute liver failure, cirrhosis, and people who have failed prior treatment for hepatitis B and C.
