Cristian D. Valenzuela, M.D.

  • Assistant Professor of Surgery, Division of Surgical Oncology, School of Medicine


Dr. Cristian Valenzuela is a Chilean-American surgeon, born and raised in the New York City area. A desire to serve the less fortunate led him to pursue his surgical residency at a New York inner-city public hospital in Spanish Harlem. He also has a passion for basic science research, which led him to pursue laboratory projects focused on blood vessel and tissue development. After completing his general surgery residency, he sub-specialized in cancer surgery at Wake Forest University. He then joined the OHSU surgical staff, and his surgical focus primarily includes treatment of melanoma and sarcoma.

Outside of work, his hobbies include running and hiking, piano, chess and watchmaking. He is married and a father of two.
