About me

Dr. Pegna specializes in the care of adults with cancers of the gastrointestinal (GI) and neuroendocrine systems (NETs). He is additionally interested and experienced in the management of rare tumors including pheochromocytomas, paragangliomas and adrenocortical carcinomas. Dr. Pegna is actively involved with clinical trials and cancer research to improve survival and quality of life for cancer patients and to better understand the biology of these diseases. He specializes in the use of chemotherapy, immunotherapy and multidisciplinary approaches to cancer care. Dr. Pegna finds it rewarding to help patients understand their disease, providing treatment options based on each individual patient, and supporting them through their treatment journeys. Dr. Pegna grew up in Upstate New York in a French-speaking family and goes by either Guillaume or Will, the English translation of his name. Although he has spent most of his life on the east coast, Dr. Pegna, along with his wife and two children, were very excited to move to Portland.

Outside of work, he enjoys hiking, ice hockey and traveling with his family. He very much looks forward to exploring the sights and tastes of his new home here in Oregon.

Insurance

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.
