Group Health Cooperative

Group Health Cooperative, formerly known as Group Health Cooperative of Puget Sound, later more commonly known as Group Health, was an American nonprofit healthcare organization based in Seattle, Washington. It was acquired by Kaiser Permanente in 2017 and now serves as the Kaiser Washington region. The new region would serve the majority of Washington state except for the Southwest Washington counties of Clark and Cowlitz, which would continue to be served by the Portland-area Kaiser Permanente Northwest.
