Our beautiful parish has a 155 year history here in O’Fallon! I invite you to join us, as a visitor or as a member of our loving 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 in for a visit to find Christ here... and bring Christ to the world.
Peace, Fr. Nick
