About Evan S. K. Ong

Dr. Evan Ong most recently received the 2023 Cancer Surgery Top Doc designation and has received the Seattle Top Doc award for multiple consecutive years. Dr. Ong's clinical practice focuses on the treatment of all gastrointestinal cancers with particular interest in treatment options for pancreatico-biliary cancers as well as regional and metastatic disease. He offers state-of-the-art treatment including minimally invasive and robotic surgery for hepatic and pancreatic tumors, microwave and bipolar radiofrequency ablation, irreversible electroporation (Nano-knife) as well as Hyperthermic Intraperitoneal Chemoperfusion (HIPEC), a treatment option for cancers that have disseminated to the peritoneal cavity. Dr. Ong's philosophy of care is "Qui Audet...Cura" - "Who Dares...Cures."
