Founded in 1949, St. Mary's High School is a Roman Catholic, Parochial, coeducational, college preparatory school serving the diverse educational needs of families in the Diocese of Rockville Centre and the Diocese of Brooklyn.

St. Mary's High School is conducted by dedicated Lay and Religious men and women who value their ties to the Sisters, Servants of the Immaculate Heart of Mary, and the Marist Brothers and continue their commitment to preparing young men and women for college and life-long learning.

While celebrating the uniqueness of each individual, our mission calls us to continue our tradition of spiritual development, academic excellence, friendship, service, responsibility, and citizenship into the twenty-first century.

Spirituality

At St. Mary’s High School, our educators seek to blend intellectual formation with a religious vision, and academic freedom with fidelity to the Catholic tradition. Our diverse student population works together everyday with the faith that “All are one in Christ.”

St. Mary’s strives to develop knowledge in our students from the perspective of service and justice in school, in church, and with all humanity. In each of the four required religion courses, students explore the Bible as well as subjects such as morality and ethics in modern society.

St. Mary’s Campus Ministry offers many programs to meet the spiritual needs of our students. Day and weekend retreats are available to students in each grade. Campus Ministry also provides opportunities for community service, group Bible Study, training for Eucharistic Ministry and Retreat Leadership.

Furthermore, the student body is a welcome part of St. Mary’s Parish family. Students are served by two priest chaplains, attend school liturgies and prayer services, and they are welcome to spend free time in the church for prayer or meditation.
