In 1947, a group of Christians living in the Allenton, Missouri area contacted Rev. Martin Olsen, then Pastor of St. Paul's Lutheran Church in Grover, Missouri, about holding services in the Allenton area. Services began on Easter Sunday evening, April 16, 1947. St. Marks Evangelical Lutheran Church of Allenton was officially organized as a congregation June 9, 1948. Needing a worship center of their own, the members themselves started construction of a church on September 24, 1950, and the first building was dedicated on August 5, 1951. The Church continued there under the shepherding of various part-time pastors and two full-time pastors. Pastor Dr. Lorenz Wunderlich, Professor at Concordia Seminary, served as part-time Pastor for 10 years. The two full-time Pastors were Rev. R.C. Radde, (1964-1967), and Rev. William Schulz, (1968-1970).

St. Marks broke ground on Easter, 2000, to build a new Worship Center, office complex, expanded child care facilities and the conversion of the present sanctuary to a Youth Center, media center, library, classrooms and additional support offices. These new facilities were dedicated to Gods Glory and to serving people on Easter, 2002. St. Marks purchased 7.38 acres just south of the new Worship Center in December, 2002 and a new senior apartment facility was opened in the fall of 2004. These apartments are for low income seniors and are managed by Lutheran Senior Services of St. Louis. In January of 2005, Pastor John Jameson became Lead Pastor at St. Marks, replacing the then Senior Pastor Pastor Darwin Karsten. On August 1, 2006 Pastor Karsten was called to be the Ozarks Regional Mission Coordinator to oversee the planting of new churches along Highway 65 between Springfield and Branson. Pastor Karsten was installed in his new position at Faith Lutheran Church in Branson on September 10, 2006. St. Marks anticipates an exciting future as God blesses the ministry of its church and school as we work together to make disciples of Jesus Christ.
