Founded in 1922 with the motto "Character Before Career," The Stony Brook School is a boarding and day school that educates young men and women in matters of the mind, body, and heart.
Students are trained to be leaders with integrity and virtue.
We find that character is essential to the development of the whole person and maintain a spiritual component to the education process. While students are presented with the truths of the Gospel of Jesus Christ, they are free to maintain their own personal spiritual beliefs.
We welcome you to our campus for our open houses, campus tours and for discussions with our Admissions team.
Our virtual tour will take you through our facilities.
