In June 1971, St. Joachim’s welcomed their new pastor, Father William L. Cotterall. Where changes to the liturgy were seen under Father Fagan the changes to the church as a result of Second Vatican came under Father Cotterall. With the liturgical changes it was evident that the church was no longer adequate. Revamping of the sanctuary included placing the altar, the pulpit and the baptismal font closer to the people, painting of the vestibule, removal of the old confessionals and installation of two combination confessionals. Also conference rooms with air conditioning were built with speakers so that parents of little children could participate in Mass. The altar railings were removed and the floors were carpeted to keep the church warmer in the winter. Father Cotterall also made $60,000 worth of renovations to the school building. Father Cotterall remained pastor until June 29, 1978 when he was reassigned to Nativity B.V.M.
