As a not-for-profit health plan created by local doctors and their hospitals, Western Health Advantage offers a refreshing alternative to the expensive bureaucracy of national HMOs.

Fifteen years ago, UC Davis Health System, Dignity Health and NorthBay Healthcare System came together to create a health plan to offer clear value in quality care for the people who live and work in Northern California. And this care starts with the exceptional range and reputation of our health care providers.
