First Unitarian Church of Salt Lake City is part of the UUA Mountain Desert District. The District includes UU Churches in Colorado, Idaho, Montana, Nebraska, New Mexico, Texas, Utah and Wyoming.

The MDD serves as a resource, an information center and a clearinghouse for district congregations and their leaders, as well as for district volunteers. MDD provides leadership training, district wide meetings and provides opportunities for UU churches to participate in projects and activities which allow us to share our common goals.
