About

Our Campuses

One School, Two CampusesOne mission since 1917, now lived out on two Lake Forest campuses.

A School of St. Mary education unfolds across two campuses, each suited to a different stage of a child’s growth. Our youngest students begin at the Primary Grade Center in West Lake Forest and continue at the Upper Grade Center downtown. One community and one mission guide each child from age two through eighth grade.

Primary Grade Center (PGC)

Preschool through 3rd Grade · West Lake Forest
The Primary Grade Center is where a School of St. Mary education begins. On our west Lake Forest campus, alongside St. Patrick Church, our youngest Crusaders learn in bright spaces suited to early childhood. Wide hallways and floor-to-ceiling windows fill the building with natural light, and our preschoolers enjoy a separate entrance and a contained playground all their own.

Upper Grade Center (UGC)

4th through 8th Grade · Downtown Lake Forest
The Upper Grade Center carries that foundation forward. On our downtown campus, part of the historic Church of St. Mary parish, students in 4th through 8th grade step into a more independent stage of learning. A dedicated Science Lab and STEAM Lab support hands-on inquiry, and the parish setting keeps faith at the center of the school day as students prepare for high school and beyond.

Planning a Visit?

The best way to know a school is to walk its halls. We would love to welcome you to either campus.

Prospective Families

We would love to show you our classrooms and introduce you to our community. Schedule a tour of the campus that fits your child’s age, or visit both.

Alumni and Former Students

We love welcoming our alumni home. To protect our students’ learning time, please arrange every visit in advance. Please email Mrs. Haak at mhaak@schoolofstmary.org to arrange a time, and we will coordinate with the school office. Because staff availability and academic needs come first, we cannot accommodate drop-in visits. When you arrive, please check in at the main office and wear a visitor badge.
