At St. Mary School, education is more than academic preparation. It is the formation of the whole child—mind, body, and soul.
In partnership with parents and rooted in the life of the Catholic Church, we help each student grow in faith, wisdom, virtue, and love. From Children’s House through eighth grade, students are known, challenged, and encouraged to become the people God created them to be.
