School Reviews

5 5/17/2016

St. Mary Immaculate has been an answered prayer. The teachers are all excellent - truly. The facility is beautiful and everyone is genuinely invested in the success of students. The sense of community is great, too. Really nice families who put God and their faith, first in their lives. We absolutely love it and recommend it highly. The one downside is a music program that doesn't really exist. Wish that could be fixed.
