About Our Parish

St. Margaret Mary Alacoque Parish was established on April 30, 1962, when Fr. Joseph O. Scheer, then pastor of Holy Angels Parish in Kinloch, received a letter from Archbishop Ritter instructing him to establish a new parish on nine undeveloped acres in the Mattese area.

The patronage of St. Margaret Mary Alacoque was granted to the new parish at the request of Herb and Agnes Faust, the prior owners of the land. Through St. Margaret Mary’s intercession and by the grace of Jesus’ Most Sacred Heart, 125 families and a huge sinkhole were transformed into the home of a faith community, dedicated in the spirit of “family.” 

Our neighborhood parish is now home to more than 2300 families. We are an anchor in the Southern Vicariate, and we look forward to serving this region with a strong core community for many years to come. With gratitude and affection, we celebrate our 63rd anniversary this year.

A Neighborhood Parish

Located in a residential area of South St. Louis County, St. Margaret Mary Alacoque is a uniquely neighborhood-based faith community. Our peaceful campus and fields are a popular local destination for people walking pets and enjoying the area.

It is our joy to help bring Christ to the community. We’re lifting one another up in prayer, so that no one should feel lost or alone in the “shuffle” of the modern world.
