In the fall of 2000, several families began meeting for a Bible Study in the Parker area. This was to become the nucleus of Reformation Church. The church met for worship for the first time on February 4th, 2001 in the Lutheran High School of the Rockies’ multi-purpose room at 10435 South Parker Road. Kevin Swanson led the worship at the first service and continued as a ruling elder of the church for about one year. During this time, the church was accountable to the elders of Providence Presbyterian Church in Denver. The church quickly grew from an attendance of about 50 to 150. On April 12th, 2002, Kevin Swanson was ordained as a teaching elder, Jim Mill was ordained as ruling elder, and the church voted to establish itself as a particular church. Mike Chapa and Bob Fine were added as elders on March 2008. Bill Roach was added to the eldership in 2013.

In the late summer of 2002, the church, then made up of families from Colorado Springs, Monument, Divide, Evergreen, Littleton, Elbert, Kiowa, Parker, Castle Rock, Aurora, and Highlands Ranch, chose to move to Castle Rock as a more central location. For six years, the church met in the Douglas County High School facilities, moving into the Clear Sky Elementary School in 2010. By the fall of 2008, the church had over 250 adults and children accounting for the member households in the congregation.

In the spring of 2013, the members of Reformation Church voted to construct a building in Elizabeth, Colorado. At the same time, plans were laid to form a mission work in Castle Rock. Attendance was regularly exceeding 300 and space was limited at the Elementary School. The Elizabeth building was completed in April 2014 and Reformation Church of Elizabeth formed in May 2014. At the same time, Elders Mike Chapa and Jim Mill stayed in Castle Rock to develop the Emmanuel OPC mission work.

Reformation Church of Elizabeth continues weekly Lord’s Day worship services in Elizabeth and daily discipleship among families and members of the church seeking to spread the good news of Jesus Christ in Elbert County.
