St. Mary of the Assumption School was established as a parish school in Brookline, Massachusetts in 1899. During its early years, the school was staffed by the Sisters of Notre Dame de Namur and later by the Sisters of St. Joseph. The school population consisted of students of mostly Irish and Italian descent from Brookline and area neighborhoods in Boston.
Today, the school has a faculty of full time lay teachers as well as learning support specialists. The school staff also includes classroom aides, a librarian, and instructors in art, music, and physical education.
St. Mary’s builds on a rich tradition of Catholic education. We serve a diverse population among which a total of over 20 different languages and 25 different communities are represented. Our culturally diverse community enriches and strengthens students who are guided by the pursuit of a virtuous life.
