Founded by the School Sisters of Notre Dame in September 1914 with 160 students, St. Mary School is proud next year to be celebrating 100 years of providing Catholic education to the families of Long Island. The dedication of administrators, faculty and staff committed to Catholic education over these years has caused St. Mary School to thrive. The school presently serves over 500 students, from Nursery through grade 8. Fully accredited by AdvancED, St. Mary School each year graduates students who overwhelmingly choose to continue their education in Catholic High schools and are accepted by their first choice of school.
