About University HealthCare Alliance

University HealthCare Alliance (UHA) is a medical foundation born out of the aspiration for Stanford Medicine and local, high-quality providers to partner together to bring a greater range of leading edge health care services to patients within surrounding communities.

UHA was formed January 1, 2011 as a 1206 (L) Medical Foundation organized to operate and own medical practices. UHA is comprised of four medical groups with over 70 clinic locations and over 350 board-certified primary care and specialty care providers located across Bay Area communities. UHA also includes an affiliated IPA network – Affinity Medical Group – which provides additional high-quality, innovative, and affordable health care solutions, to give our patients the choices, flexibility and high standards of quality care they deserve.

UHA is truly contributing to Stanford University’s well-respected hospital and clinic’s transformation into a high-performing health system. Together, UHA and Stanford are pioneering new ways to practice medicine across multiple locations, using Stanford’s advanced resources to create seamless continuity of care for every patient.
