Community Bible Church in St. Regis is one of the oldest member churches of the RMBM. The work began, ironically, with a youth group 15 miles down the road at Westend (DeBorgia). The Westend youth group was so popular that it attracted kids from St. Regis, who eventually asked the Mission for a group of their own. From that youth work an adult Bible study was begun, and later a church was established.

St. Regis is almost exclusively a timber industry town, peopled by loggers, mill workers and some railroaders. The town of about 700 inhabitants is situated at the junction of the St. Regis and Clark Fork Rivers, about 75 miles west of Missoula on Interstate 90.
