SUPPORT OUR RAFFLES

The real blessings at St. Mary's South Side Catholic High School are the wonderful, talented, and thoughtful young men that walk the halls each day.

Our student body has the most diverse population of any private Catholic school in the St. Louis region. It is not only ethnically diverse but culturally, socio-economically, religiously, and geographically. It's a school where students learn from and about each other and call each other brother. Our dedication to developing responsible young men who are prepared to live as contributing and successful members of society is more critical today than ever before. Our young men are the bright, bold leaders of tomorrow that will create better communities for our region.
