Interfaith began with a concerned group of people consisting of clergy, social service agency directors, and other interested persons who formed the Interfaith Council. This effort originated in February 1982, when a Church Women United Committee was appointed to investigate ways to meet the needs of the increasing number of people requiring emergency food and shelter. It was apparent that many were falling through the cracks of the existing system for emergency needs.

Casper ministers, social service agency directors, and interested persons met in a workshop sponsored by Church Women United. Many different approaches to the problem were considered. It was originally decided to concentrate efforts on a central clearing house and permanent housing for families. Interfaith began serving persons who needed emergency assistance in October 1984. The first family went into transitional housing in November 1984.
