Kaiser Permanente, formerly Group Health, offers health insurance and medical care in Washington state. The Seattle-based Cooperative offers a unique health care system, care delivery, and health coverage, in order to achieve one goal—affordable, quality health care for all. Our innovative practices at 25 medical centers and within major Washington hospitals have earned national recognition for medical quality, disease prevention, and evidence-based treatments. These priorities have remained the same since we began serving patients in 1947.
