Our parish has a 150 year history here in O’Fallon and I invite you to join us, as a visitor or as a member of our parish family, as we continue that history of striving to follow Christ. I hope this website can answer your immediate questions but you are always welcome to contact us personally, or better yet, to stop by where we hope you will find Christ here, and help us bring Christ to the world.
Peace, Fr. Nick
