Letter from the Program Director
To make your surgical education a rewarding and enriching experience, we partner with state-of-the-art hospitals, progressive clinics, and dedicated, knowledgeable physicians across five training sites: - Riverside University Health System (RUHS) Medical Center - Kaiser Permanente Riverside - Kaiser Permanente Moreno Valley - Children's Hospital of Orange County (CHOC) - Loma Linda University Medical Center (LLUMC) Our program is accredited for 4 residents at each level, with an additional 4 preliminary residents in the PGY-1 year and 2 preliminary residents in the PGY-2 year. We seek to prepare residents to become surgeons of the highest caliber by providing a rich, hands-on educational experience across this variety of clinical settings. The three main program components — curriculum, research, and service — are structured to help residents acquire the knowledge, skills, attitudes, and clinical judgment needed for the practice of general surgery. Residents benefit from a deep well of teaching expertise and clinical experience throughout their training. Our goal is early exposure to the operating room and progressive autonomy from intern year through the chief resident year. PGY-1 residents have logged between 100 and 200 cases on average over the past five years. The program uses a state-of-the-art simulator as part of the skills curriculum throughout training, and residents gain broad, extensive experience in trauma and acute care surgery at RUHS Medical Center — one of the busiest trauma centers in the area and an American College of Surgeons–accredited center. The RUHS/UCR General Surgery Residency Program has a strong commitment to the underserved population of Riverside County. Making a positive impact on a large, multicultural population gives our residents rewarding experiences that stay with them for a lifetime. Our goal is to train exceptional surgeons who, upon completing their training, choose to stay in or return to this area to serve this community. We hope this window into our program gives you a genuine sense of who we are, and inspires you to learn more about our program offerings, our institutions, and what gives General Surgery Residency Education at RUHS its sense of purpose and mission.
