San Antonio Regional Hospital’s Center of Aging provides expanded healthcare services to address the needs of our region’s growing Medicare-age population. Located in Rancho Cucamonga, the Center houses multiple providers for seniors in a “one-stop shop” concept. This includes primary care physicians and specialists such as orthopedists, cardiologists, geriatricians, audiologists, and more. Imaging services, pharmacy, lab, and physical and occupational therapy are also offered in the same building.
San Antonio's Center of Aging will be transformative for those in the aging population and those who care for them. The Center is designed to streamline geriatric services and help seniors stay as independent as possible, enhancing the quality of life for all involved.
