School Reviews

Catholic or not, this is where you want your kids. They have generous scholarships — just ask. All grades learn Spanish. The math curriculum is robust. PE 4 days a week. My 8-year-old is picking up books and reading for fun. The school culture is radical generosity, appreciating each individual child for their gifts. It's not elitist at all - a stellar education made possible for working-class families. In my daughter's time there, she hasn't mentioned bullying or teasing once. St Mary's = happy, loving well-educated kids.
