On behalf of the entire St. Theodore Parish family, we would like to welcome you to St. Theodore Parish!

As you may have already known, St. Theodore Parish is a growing and active parish. We have found that it is helpful to explain a little about our parish community and the people who worship, play and work together as the body of Christ.

St. Theodore Parish was founded in 1883. St. Theodore School has both old and new facilities. The old section of the school was built in 1913 and the new section of the school, along with the state-of-the-art Parish Center, was built in 2001. We are all very proud of our new addition to the school as well as our new parish center.  We would have never been able to complete this 3.2 million dollar project without the blood, sweat, and tears of every single parishioner and our loan is now paid in full.

Our parish thrives on the commitment of time, talent, and treasure of all its parishioners. 

We could go on and on about the things our Parish does.  We are sure you have questions about St. Theodore Parish and School.  Please do not be afraid to ask. Feel free to ask any questions you may have to our parochial administrator, Fr. Peter Fonseca after mass any given weekend or just call the parish office at 636.332.9269.
