About St. Mary's High School


St. Mary’s High School, founded in 1931, has been an integral part of St. Louis’ South Grand’s Dutchtown neighborhood. The campus includes more than 27 acres, encompassing a blend of state of the art academic classrooms to modern sports facilities, including the Center for Applied Sciences (CAS), baseball field and soccer practice facility.

St. Mary’s remains on the leading edge of secondary education and has continued to accomplish this at a tuition cost that is significantly less than other all-male secondary schools in the St. Louis area. The more than 12,000 graduates can testify to the quality of the St. Mary’s High School academic curriculum. However, academics is only one portion of the education students receive. Rich in Marianist tradition, over four years, students are encouraged to explore their minds and grow not only academically but personally, spiritually and athletically.


Coat of Arms of St. Mary’s High School

The figure of Our Lady of the Pillar signifies the origins of the Society of Mary. It was at the shrine in Saragossa, Spain (where Chaminade was in exile from 1797-1800) that Blessed Chaminade was inspired to found the Society of Mary and the Daughters of Mary Immaculate.

The SM on the seal stands for Saint Mary.

The cross is a reminder of the life and death of Jesus.

The scroll with Fortes in Fide (Strong in Faith) is a summary of the teaching of Blessed Chaminade and the spirit of the Marianist Family. It is through faith that we accomplish our mission.

The scroll with Per Matrem ad Filium (Through the Mother to the Son) is the dominant idea for the Society of Mary and the Family of Mary.

The lilies and roses signify Mary as the unspotted lily and mystical rose who wishes to see in our hearts the lilies of innocence and roses of charity.

The fleur-de-lis and the crown refer to St. Louis.
