We are new to Saint Mary this year and we already know we made the right decision for our two kids who are in 3 and 6 grade. Our kids are loving the teachers which is a deal breaker for me because my older wasn`t happy at the last school. We are here to stay!

Our kids love Saint Mary School and the excellent and very dedicated teachers there. Although the institution is ill-equipped to nurture "outliers", it does a good job with the relatively homogenous population of students it serves overall. Again, I've yet to meet a teacher that was not completely committed to the biopsychosocial growth of our children. The administration is tolerable and our encomiums go, as they should, entirely to the excellent teaching staff at SMS.

WE LOVE Saint Mary. We sent our 4 year old to preschool there thinking we would move to the public school for kindergarten. NO WAY. 3 years later we are now sending our next child to the preschool and our 2nd grader is so happy and loves going to school each day to see her teacher & friends. she also loves telling us about her day and what the "big" kids are doing that she wants to do when she gets older. It's a great family environment and has an outstanding curriculum. My daughter loves her library time, music class and spanish - wow. I highly recommend Saint Mary School

St. Mary is a wonderful environment for children to learn and grow as individuals. They are constantly advancing their academics and keeping pace with technology all while offering music, art & many other extras at no extra cost. It is a safe and welcoming community for all our children, where everyone knows their name. I highly recommend PreKthru 8th grade.
