Mt. Olive's second house of worship was dedicated to the glory of God in November 1932, only three months after the groundbreaking ceremony and exactly 37 years after the dedication of the first building.  On that day, the Mt. Olive congregation numbered some 120 souls.

   During the 1930's there was much excitement in the congregation when the church's first pipe organ was built, installed and dedicated.  This organ provided years of beautiful music before being dismantled and moved to the third sanctuary in 1968.

   During Rev. Long's final illness, the congregation had been faithfully served by Rev. O.W.H. Lindemeyer, a professor at Concordia College.  He accepted the congregation's call following the death of Pastor Long.  Rev. Lindemeyer served until 1952, during which time the spiritual community of Mt. Olive continued to grow and prosper.

   In 1953, Rev. Margold W. Harman accepted the call to Mt. Olive.  His pastorate was especially noted for the fact that the congregation grew too large to be accommodated by the existing facility.  The congregation took on the challenge of planning and constructing a new building.  Led by Pastor Harman, the congregation built a beautiful modern facility on land obtained from Rev. and Mrs. Brandon, a site located directly across the highway from the 1932 building.  This building was designed to serve not only the congregation existing at that time, but also to expand for future growth.  Dedicated to God's glory in 1968, this third sanctuary still stand and serves as a testimony to the faith and determination of a congregation and its pastor.
