75th Anniversary

Celebrate 75 years of Catholic Education

It was the auspicious confluence of the Parish Priests; Congregation of the Sisters, Servants of the Immaculate Heart of Mary; and the Marist Brothers of the Schools in Manhasset which gave St. Mary's High School its promising start in 1949. Their combined mission to make Jesus Christ known and loved in the hearts of their pupils through devotion to Mary, His Mother laid the foundation of a school wonderfully made. 
 
75 years later, St. Mary's continues to stand at the forefront of Catholic education on Long Island, giving young people opportunities to excel in academics, athletics, and the arts while keeping the Truth of Christ at the center. Let us honor this legacy by celebrating some of our outstanding community members and supporting the mission of St. Mary's for future generations of students.
