Although the Coon Prairie congregation was formally called together to consider calling Peder Asbjorsen as pastor in July 1854, the first Coon Prairie sacramental records date from Pastor Nils Brandt's book of 1851. However, this log book was probably started in 1852 and the pastor filled in the previous year's records from memory.

In July 1855 Pastor H. A. Stub became Coon Prairie's first pastor. His parish consisted of the widely spread Coon Prairie congregation (at that time 25 miles long) and the 20 mile long Coon Valley with its three smaller congregations. This included nearly the western half of Vernon County and part of Monroe County.

A church was erected by the congregation and was completed by June 1857. It was the first Norwegian church to be built in western Wisconsin and the first of any kind to be built in Vernon County. The dedication ceremony took place June 1858. In the fall of 1861, the congregation joined the Synod of the Norwegian Evangelical Lutheran Church in America.

Pastor Stub was well liked but because of ill health decided to return to Norway in 1861. Pastor A. C. Preus left Our Savior's church in Chicago to become the permanent pastor at the Coon Prairie parish in June 1863. During this time the issue of slavery created a rift between many Midwestern congregations and the Synod. In the end, the Coon Prairie congregation adopted the following resolution: "Slavery is sin without exception among Christian and civilized people." Due to ill health, Pastor Preus found it necessary to resign his pastorate in 1872 and returned to Norway.

Reverend Halvor Halvorsen, one of Coon Prairie's most beloved pastors, was installed in 1872. At this time, the Coon Prairie congregation numbered about 1200 people. Pastor Halvorsen also ministered to the Coon Valley congregations, Kickapoo, Portland, Brush Creek, North Coon Prairie, Viroqua, West Coon Prairie, Vang and La Farge, during the course of his 492 year tenure at Coon Prairie charge. Various divisions were made and separate parishes formed over time so that by 1894 the Coon Prairie charge consisted of the Westby-Coon Prairie and Vang congregations.

Because the original church at Coon Prairie had become too small, a foundation was laid for a new church building in September 1875. The congregation began using the new church in 1878, and the cost of the project was $25,600. The dedication ceremonies took place much later in 1884. By 1886, Coon Prairie's membership was about 1670 souls, and was one of the largest Norwegian-American congregations. In 1888, about 50 families withdrew and formed Our Savior's Church in Westby.

The Coon Prairie's church building was complete with a spire in 1891. Unfortunately the church was struck by lightning and burned to the ground on Easter Sunday 1909. Where to rebuild the church was not determined easily. In the end, the congregation constructed two churches at a cost of $22,000 each located within 12 miles of each other. One church occupied the original site and the other church was erected in Westby.

Reverend Halvorsen died in 1921 while on one last trip to Norway to visit relatives. He was interred in Coon Prairie cemetery. His successor, the previous assistant pastor Reverend J. O. Holum, was installed as pastor. He resigned in 1947 to accept a call from Central Lutheran Church in Minneapolis. Pastor H. O. Aasen succeeded Holum. In 1949 the church name was changed from Norwegian Evangelical Lutheran Congregation to Westby-Coon Prairie Lutheran Church. In that same year, women were given the right to vote. By 1950, extensive repairs were done to both the Westby and Coon Prairie churches. In 1951, the congregation numbered 1896 persons.
