School
History
St. Sebastian's School was founded in 1941 by William Cardinal O'Connell, Archbishop of Boston. In keeping with the spirit of the age, the School was named for Sebastian, the soldier - saint. St. Sebastian continues to be a role model for our boys. His values of integrity, leadership, courage and faith have never been more vital. Our 340 boys in grades seven through twelve dare to share freely and fully of themselves as they grow in body, mind, and spirit.
