The Department of Surgery at the University of California, San Francisco is one of the leading surgical departments in the world. It has a rich history of scientific, educational, and clinical advancements. Our care is dedicated to the people of San Francisco and California, but our reputation draws patients nationally and internationally. We are one of the largest clinical services at UCSF performing a high volume of procedures. This allows our surgeons to continually improve their skills, resulting in better outcomes for patients.

To better care for patients, we have six major San Francisco Bay Area hospitals: UCSF Medical Center at Parnassus, UCSF Medical Center at Mt. Zion, UCSF Medical Center at Mission Bay, Zuckerberg San Francisco General Hospital (ZSFG), San Francisco VA Medical Center (SFVAMC), and Highland Hospital, in Oakland through our UCSF East Bay Program. Both ZSFG and Highland are Level 1 Trauma Centers.
