About PeaceHealth PeaceHealth, based in Vancouver, Wash., is a not-for-profit Catholic health system offering care to communities in Washington, Oregon and Alaska. PeaceHealth has approximately 16,000 caregivers, a medical group practice with more than 900 providers and 9 medical centers serving both urban and rural communities throughout the Northwest. In 1890, the Sisters of St. Joseph of Peace founded what has become PeaceHealth. The Sisters shared expertise and transferred wisdom from one medical center to another, always finding the best way to serve the unmet need for healthcare in their communities. Today, PeaceHealth is the legacy of the founding Sisters and continues with a spirit of respect, stewardship, collaboration and social justice in fulfilling its Mission.
