On December 7, 1941, a Sunday School class of 16 peope met in a humble, sawdust-floored building to dedicate it to the Lord. Under the strong leadership of Pastor W. A. Buell, the independent church began to grow and felt the need for affiliation with an already-established denomination. Under the leadership of Rev. E. V. Perkins, the Falls Avenue Wesleyan Methodist Church was organized on January 21, 1946, by Rev. William Dyer, Conference President. There were six charter members.

In March of 1945, a building known as the Waterloo Gospel Tabernacle was purchased and REv. E. V. Perkins was appointed pastor. Prior to that time, the tabernacle had been maintained as an independent Gospel work under the direction of Rev. W. A. Buell.

In May of 1946, the United Brethren Church of Fairview, Iowa, was purchased and moved in sections to 2222 Falls Avenue. It was dedicated on March 6-7, 1948. A new parsonage was started on December 29, 1952, and completed in the spring of 1953. An additional four lots around the church were purchased with the view of expansion. Under the leadership of Rev. Spencer Moon, a new church was completed with sanctuary seating for 250. In 1967, a large education wing was completed which added 20 more classrooms and a fellowship hall that seats 250. In 1969, a split-level parsonage was purchased to replace the parsonage built in 1953. A new sanctuary was erected at 3520 Ansborough AVenue in Waterloo. In 1975, an educational wing was added. In 1999 a worship/drama center, multi-purpose room, a new kitchen, and new classrooms were added.

Cedar Valley is the largest church in the District with multiple staff positions and state-of-the-art facilities.
