About Kaiser Permanente

Kaiser Permanente is an American integrated healthcare organization that combines health-insurance plans, hospitals, medical offices, pharmacies, physicians, and other care services. Its structure is designed to coordinate coverage and healthcare delivery across connected regional organizations.

Kaiser Permanente was founded in 1945 by industrialist Henry J. Kaiser and physician Sidney R. Garfield. The organization developed from healthcare programs serving construction and shipyard workers into one of the largest nonprofit healthcare systems in the United States.

Kaiser Permanente is headquartered in Oakland, California, and operates regional health plans in California, Colorado, Georgia, Hawaii, Maryland, Oregon, Virginia, Washington, and the District of Columbia. Member-service numbers, complaint procedures, medical facilities, and plan benefits vary by region.
