School Notes

  • LEGACY
  • Founded in 1949, Saint Mary’s High School was first staffed by the Sisters, Servants of the Immaculate Heart of Mary and Diocesan priests. The first classes were held in the parish elementary school. The following year, 150 boys and girls continued their studies in the new high school building erected on the campus; later that year the Marist Brothers arrived. We honor our founding principals, Mother M. Annette and Brother Nicholas Mary, who set the foundation of the Saint Mary’s High School education that has guided and served the school for over 60 years.
  • PHILOSOPHY
  • Empowering Character, Innovation, and Leadership in our students, Saint Mary’s High School is a dynamic, contemporary, Catholic value centered school, combining a commitment to academic excellence and educational innovation, with a passion for learning, and an emphasis on moral character development through the pursuit of truth as discovered in faith and reason. Saint Mary’s transforms the lives of its students and our community through the power of learning and academic excellence, preparing young people to assume a life of integrity, academic success, career fulfillment and service to the community.
  • CAMPUS
  • St. Mary’s is located off Northern Boulevard on Clapham Avenue and Second Street in Manhasset. The high school facilities provide its students with the use of 42 classrooms, state-of-the-art science labs including two biology centers, two chemistry, one earth science, and one physics laboratories, three computer rooms, a library,  two gymnasiums each with locker room facilities, two art studios, an auditorium, two cafeterias, and an all-weather soccer/lacrosse athletic field with a track.  The parish has made its church available for all school liturgies and prayer services.
