Founded 15 May, 1895
In December, 1894, Holy Trinity Lutheran Church on Main Street purchased land on the southeast corner of Elmwood and Highland with the intention of establishing a mission in the area. William Hengerer, of the department store fame, held the land in trust until the establishment of the congregation on 15 May, 1895 with 59 charter members.

The congregation prospered and within a year, 15 April, 1896, it became an independent church. It soon outgrew the frame chapel erected on the site and began looking for new property on which to expand. They purchased land on the west side of Elmwood north of Highland but the site later proved to be too small for its
intended purpose. In 1911, they purchased the present lot and disposed of all other church property.

Ground was broken for the new church 2 July, 1912. While construction progressed, the congregation utilized the Richmond Avenue Methodist Church. on 27 November, 1913, they formally dedicated the $50.000 house of worship.
