In August 1890,
nuns of the
Sisters of St. Joseph of Peace moved to
Fairhaven, Washington, from the convent in
Newark, New Jersey, to establish a hospital for loggers;
St. Joseph Hospital opened in January 1891. At the time, PeaceHealth had annual revenues of approximately $1.3 billion and operated seven hospitals. The organization announced an alliance with
University of Washington Medical Center in May 2013, which the
American Civil Liberties Union criticized due to PeaceHealth following Catholic medical care directives. PeaceHealth acquired
ZoomCare in 2019. PeaceHealth changed their logo in spring of 2023, to better reflect their focus on "whole person wellness". On May 22, 2025, PeaceHealth reduced it's workforce by 1% and implemented a hiring freeze through the end of 2025. All PeaceHealth employees received an email from Richard DeCarlo, executive vice president and COO, and Sarah Ness, executive vice president and chief administration officer that said certain programs and workforce across Springfield, Ore.-based PeaceHealth, Sacred Heart at RiverBend Medical Centers, and Vancouver-based PeaceHealth SouthWest Medical Center would be affected by the reductions. ==PeaceHealth Medical Group ==
