Background and History

Jiva Health was established in 1977 and has operated as a family-owned, multi-specialty medical group for over 40 years. What began as a practice serving the Antioch, Concord, and Walnut Creek areas has grown into a regional group with multiple East Bay and Sacramento-area locations.

The practice combines primary and chronic care with a range of specialties, positioning itself as a single medical home where patients can address weight, metabolic, sleep, and allergy concerns together. Its weight-related care is intentionally connected to the conditions that often accompany weight gain — diabetes, heart disease, and sleep disorders — reflecting the group’s prevention-focused philosophy.
