Welcome to Gonzaba Medical Group
More than 60 years ago, Dr. Bill Gonzaba implemented a model that would positively change the quality and accessibility of medical care forever. What is now nationally known as the “full-risk” healthcare model puts the patient at the center of the practice and was pioneered by Gonzaba Medical Group, the first locally-owned medical group in San Antonio.
“I wanted to bring quality medical care closer to home for the friends, neighbors and family I grew up with,” shares Dr. Bill. “I had watched my parents and their friends suffer because of the lack of access to medical care.”
Dr. Bill’s passion for people and vision for quality, affordable healthcare blossomed into one of the largest senior-focused medical practices in the city. With three state-of-the-art medical centers and four neighborhood clinics, Gonzaba Medical Group provides comprehensive healthcare and treats each patient with compassion, Como Familia-Like Family.
