Saint Louise de Marillac

St. Louise de Marillac was established on May 25, 1961.  The parish was created to meet the needs of the growing community of Upper St. Clair.  The first Mass in the new parish was celebrated on June 3, 1961, in the St. Clair Township Municipal Building.  The municipal building soon proved to be too small to meet the needs of the congregation and Sunday Masses were then moved to Fontbonne Academy.

Meanwhile, the parish made plans to construct a building that would hold a school and a temporary church.  Ground for the church/school building was broken on October 21, 1962.  The first Mass in the temporary church was celebrated on December 25, 1963. 

The parish continued to grow.  By the late 1970's it became obvious that a new, permanent church was needed.  On March 15, 1980, ground for the new church was broken.  The cornerstone of the church was laid on October 19, 1980, and the completed church was dedicated on August 23, 1981.  The temporary church was converted to an auditorium/gymnasium.
