St. Mary School was founded in 1914 by the School Sisters of Notre Dame.  For over one hundred years, the “charism” of that religious community, which is “unity, and educating in all we do and world vision” continues to permeate who we are.

Hopefully, you will take a few minutes to visit with us online and discover the great opportunities afforded to our students.  We pride ourselves on educating the whole child with a special emphasis on his or her religious formation in the Catholic faith.

You are always welcome to come and see our wonderful school and consider joining our great school family!
