New construction project
In 1921, the sisters acquired additional property and the existing building was remodeled and served as a hospital until 1931, when a new building was constructed to accommodate Polson’s growing civic community. By the early 1950s, the 1932 building was found to be inadequate, and discussions began regarding funding for another construction project. The cornerstone of the new building was laid on July 8, 1958, and the 40-bed hospital opened in March 1960.
A lay administrator was appointed in 1974 and, at this time, the sisters withdrew from active participation in the hospital. In March of that year, the community was closed and the five remaining Religious Hospitallers of Saint-Joseph departed the town. Sisters remained on the Board of Directors, however, until 13 March 1984, when the hospital was transferred to the Presentation Sisters of Aberdeen, South Dakota.
