The origins of what is now St. Luke's Rehabilitation Institute began in 1897 when a group of Episcopalians founded a
sanatorium called the Spokane Protestant Sanitarium at Sprague Avenue and Madison Street but later moved to another location on a triangular block on North Summit Boulevard formed by West Dean Avenue and North A Street. The hospital was supported by community fundraising, in-kind donations, volunteers, and through the philanthropy of early Spokane businessmen such as
John A. Finch, Amasa Campbell, and R.L. Rutter. The hospital focused its efforts on fulfilling underserved gaps in community healthcare and specialized in caring for those with
polio, where it was a regional center for its treatment. In 1970, the hospital moved into a newly constructed complex at 711 S. Cowley Street on the lower South Hill Medical District. In 2021, St. Luke's along with
Inland Northwest Health Services (INHS) was fully absorbed and integrated into the
Providence Health & Services system and is now known as Providence St. Luke's Rehabilitation Medical Center. ==Accreditations==
