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.
