May you find Christ here... May you bring Christ to the world.

Welcome to Assumption of the Blessed Virgin Mary Parish!

Our beautiful parish has a 150 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
