Our Mission

Marquette Catholic High School, a coeducational institution of the Diocese of Springfield in Illinois, offers quality education in the Catholic tradition to families of all backgrounds. Through the Serviam motto, the Marquette Community is challenged to integrate Christ’s message into their lives, and thereby carry into the world.

History of Marquette Catholic High School

Marquette Catholic High School was founded by the Ursuline Sisters in 1927 at the request of Bishop Griffin, the Bishop of Springfield in Illinois. This school was the first coeducational secondary school in the diocese. The primary purpose of the school was to aid parents in the education of their children. The school served the people of greater Alton. The Ursulines have a history of educating the youth of the Alton area that goes back to 1859.

In 1992 the Alton Ursulines gave up sponsorship of Marquette. Bishop Daniel Ryan brought the school under the sponsorship of the Diocese of Springfield in Illinois and is presently a diocesan high school.
