Trinity Lutheran Church was founded on Aug. 24, 1884.  The congregation began its school in November, 1884, and has operated every since.  The existing church building was built and dedicated in 1929. 

The school building was dedicated on June 23, 1957.  It consists of seven classrooms, an office, the gymnasium, a kitchen and cafeteria, shower rooms for students, and lavatories for staff and students.  In August of 1978, Trinity completed an addition of three classrooms and a library.  In 1971, a ninth grade was added to the K-8 program.  The pre-kindergarten was added in 1974.  In 1987, the ninth grade was dropped as Cedar Rapids went to the four-year high school.

Additional remodeling, including the addition of eight classrooms and expansion of the kitchen, took place in 1998.  Also, an elevator was added to the church building at that time.
