Sansum Clinic

Sansum Clinic is a prominent non-profit, multi-specialty healthcare provider based in Santa Barbara, California. Founded in 1921 by Dr. William David Sansum, the first physician in the U.S. to successfully isolate and use insulin to treat diabetes, the clinic has a long-standing reputation for medical innovation. The organization operates over 20 patient care locations across the California Central Coast, offering primary care and more than 30 medical specialties. In October 2023, Sansum Clinic officially joined Sutter Health, a large Northern California-based health system, to enhance its clinical resources and expand access to care. The clinic serves approximately 150,000 patients annually and remains a cornerstone of the healthcare infrastructure in the Santa Barbara region.
