The Catholic presence in Green River, Utah, dates back to the late 19th century, coinciding with the arrival of the railroad, which brought workers of diverse backgrounds, including many Catholics. Early Catholic settlers and railroad workers gathered for Mass in homes or makeshift chapels, served by itinerant priests traveling from larger towns and cities such as Salt Lake City.
In the early 20th century, the Diocese of Salt Lake City began formally organizing Catholic communities in smaller towns like Green River. Diocesan directories from 1923 to 1925 mention the presence of Holy Trinity Catholic Church in Green River during this period. Priests from Salt Lake City initially served the area, followed by priests from Price, Utah, who occasionally visited between 1948 and 1951.
Mary Schoenberger Vetere played a key role in canvassing local Catholics and advocating for the establishment of a mission in Green River. On Easter Sunday in 1949, Father Thomas F. Butler, pastor of Notre Dame de Lourdes in Price, celebrated Mass at the home of Malcolm and Rose Politano. Fifty-two Catholics attended. By 1954, priests from Price began regularly offering Mass in Green River, moving the service location from the Politano home to the Midland Hotel.
The 1960s brought new Catholic families to Green River due to missile base activity near the town. Catechism classes were taught by Mary Schoenberger Vetere and Eileen Taylor. In 1967, Bishop Federal purchased a remodeled duplex from John Harris, officially establishing St. Michael the Archangel Mission under the care of Notre Dame de Lourdes Parish in Price.
During the 1970s, under the leadership of Father Michael J. Donovan and William M. Mobley (who later became a priest), a notable sunrise service was held on a hill near Green River. The event involved three local ministers, rugged crosses, and a large turnout from the town, with a piano trucked in for the service.
In 1974, the care of St. Michael Mission was transferred from Notre Dame de Lourdes to Good Shepherd Parish in East Carbon City. On November 3, 1984, Bishop Weigand, along with Father Donald E. Hope, pastor of Good Shepherd Parish, dedicated an expanded mission facility.
The new L-shaped room provided more space for church services and social activities, serving approximately 25 Catholic families in East Carbon City.
Today, St. Michael the Archangel Mission, located at 40 North Long Street, Green River, UT 84525, continues to serve the local Catholic community, which is largely Hispanic. The mission has 15 active families, though there are at least 60 Hispanic Catholic families living in the area.
