About

For over 30 years, St. Mary's has been a cornerstone of South Orange County — the crown jewel of the Episcopal schools founded by Father Sillers. What began as a small local school has grown into a thriving Early Education through Grade 8 community known for its warm culture, global outlook, and whole-child approach to education.
Today, St. Mary's stands at an exciting moment. We have embraced forward-thinking practices — the IB framework, global competencies, design thinking, and strategic foresight — and with our new design center, we are sharpening an educational model that truly sets us apart.
