I cherish practicing in a patient-centered and collegial environment. I am devoted to timely communication and providing high-quality care to all my patients. The trust of my patients and colleagues is the best reward for me.

Dr. Wang was drawn to the field of Gastroenterology because of the diverse disease pathologies and opportunity for both intellectual challenges and procedural skills. His clinical interests are focused on screening, prevention, and using therapeutic endoscopy techniques to facilitate the diagnosis and treatment of gastrointestinal cancers.

Dr. Wang was fortunate to have trained at multiple leading medical institutions in the US. He enjoys living in Portland because of the beautiful natural wonders and pleasant people. Dr. Wang has been very happy to establish his medical practice and raise his family here. Outside of work, Dr. Wang enjoys cooking, gardening, and spending time with family and friends.
