At a Glance

Committed to the pursuit of truth through faith and reason, St. Sebastian's is a Catholic independent day school for 375 young men in grades seven through twelve.


Named after the martyred soldier-saint, “St. Sebastian’s Country Day School” was founded in 1941 by Cardinal William O’Connell, Archbishop of Boston. Under the vision of Cardinal O’Connell, St. Sebastian’s would not only develop the mind and body, but also the soul of its students, adding a third dimension to the country day school model . The School’s spiritual mission continues to be at the heart of a St. Sebastian’s education.
