About St. Mary School
A school community built on faith, family and purpose.
For over a century, St. Mary School has helped children grow academically, spiritually and personally in a community where students are known, supported and challenged to become their best.
Our Story
More than a century of Catholic education
Since 1914, St. Mary School has served families across East Islip and the surrounding communities with an education rooted in Catholic values and academic excellence. The school experience extends beyond the classroom, helping students build confidence, character, friendships and a strong sense of belonging.
Today, St. Mary's continues that tradition while preparing students for a changing world through strong academics, technology, service, leadership and a community-centered approach to education.
