Grace Community Church and Boulder City have intertwined histories. Boulder City began as a construction town for the workers and families of the workers who built Hoover Dam in the Black Canyon of the Colorado River. Grace Community Church began as an inter-denominational Protestant religious work and was supported in April 1932 by members of the National Home Missions Council. American Baptist Church, Congregational Church, United Presbyterian Church, Presbyterian Church (USA), Methodist Episcopal Church, Disciples -United Christian Missionaries, and the United Brethren Church all supported the new Grace Community Church. The theme of the original organizing group was “Let there be one Protestant church cooperating, not a dozen competing.”
