Tradition Meets Modern Learning

Founded in 1877 by the Sisters of St. Mary of Namur, St. Mary's Catholic School has served generations of families through a tradition of academic excellence and Catholic formation. The Sisters dedicated more than a century to forming young minds and hearts, establishing a legacy that continues today.

Since 1991, our dedicated lay faculty has continued that mission by providing students with a strong academic foundation while nurturing their spiritual, social, and emotional growth.

A Community That Feels Like Family

One of the things families love most about St. Mary's is our close-knit community. Students are known by name, supported by dedicated teachers, and surrounded by peers who encourage one another both inside and outside the classroom.

Through faith celebrations, school traditions, family events, service projects, and extracurricular activities, students experience a strong sense of belonging that lasts far beyond graduation.
