About me

Dr. Sundermeyer is a specialist in hematology and oncology. He developed his interest in cancer due to the rapidly progressing science to help patients with cancer and the long term relationships that can be built with them and their families. Dr. Sundermeyer believes strongly in a personal approach that works for each patient based on all the factors of their cancer, their health and their preferences in care.

Dr. Sundermeyer relocated to the Oregon coast to join CMH-OHSU Knight Cancer Collaborative in Astoria after 15 years of practice in Philadelphia with Jefferson University. He and his family are enjoying all the Oregon outdoors has to offer, hiking, biking and beaches.

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.
