Trinity congregation held its first meeting in 1906 in Scandia Hall with Pastor H.H. Frost, Sheyenne, ND, conducting the service. In 1911, Pastor Iver Havneros organized the congregation known as the Jamestown Scandinavian Lutheran Church. The following year Pastor J. C. Wisnaes was installed as the first resident pastor.
Pastor Wisnaes served until 1921 when Pastor Joseph Johnson was installed and served for 33 years during which time the congregation was named Trinity Lutheran.
In 1954, Rev. J. A. Nestigen was installed as pastor and in that same year the congregation began the broadcast of their radio service over KEYJ, which continues today over KQDJ. Ground was broken in May of 1955 for a new church building, that continues to be our present location. The building was updated in 2002, with the addition of a gathering space, fellowship hall, music rooms, and classrooms.
Other pastors having served at Trinity are Rev. Chester Johnson, Rev. Neil Thompson, Rev. Don Richman, Rev. Sheldon Tostengard, Rev. Joseph Belgum, Rev. Nancy Kraft, Rev. Rich Ferris, Rev. Norm Anderson, Rev. Terry Anderson, and Rev. David Eppelsheimer.
