About me

Dr. Ahn is the director of clinical hepatology at OHSU. His research interests are hepatitis B, hepatitis C, liver cancer, and liver transplantation. He received his medical degree from Northwestern University and completed his residency in internal medicine at the University of Chicago and his gastroenterology and hepatology fellowship at Northwestern University in Chicago. Dr. Ahn is board certified in internal medicine, gastroenterology, and transplant hepatology. His current research studies include a multi-center trial to study the impact of antiviral therapy for hepatitis B on the development of liver cancer, and multiple studies on new pharmacotherapy for hepatitis C as well as screening and linkage of care for viral hepatitis.

Before scheduling your appointment, we recommend you contact your insurance company to verify that the OHSU Health location or provider you plan to visit is included in your network. Your insurance company will also be able to inform you of any copayments, co–insurance, or deductibles that will be your responsibility. If you proceed in scheduling an appointment and your health insurance benefits do not participate with OHSU providers, your out of pocket liability may be higher. Visit the billing and insurance section of our site for more information.
