About Us

St. Mary’s High School, founded in 1931, has been an integral part of the City of St. Louis' Dutchtown neighborhood. The campus covers more than 27 acres and includes a blend of modern academic classrooms and collegiate-level sports facilities. 

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. More than 12,000 graduates can testify to the quality of the St. Mary’s High School academic curriculum. However, academics are only one piece of the educational experience students receive. Rich in Marianist tradition, students are encouraged to explore their minds and grow not only intellectually but emotionally, physically, and spiritually.


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.
