75th Anniversary

St. Sebastian's 75th Anniversary

On the morning of September 29, 1941, St. Sebastian’s held its first ever day of classes on Nonantum Hill, the site of its first campus in Newton. Twenty-one boys were there that day, helping to make the vision of founder Cardinal William O’Connell a reality. For several years, the Archbishop of Boston had been hoping to start a new school that would combine the objectives of a country day school with Catholic values. From the outset, the School’s spiritual focus was a distinguishing quality and continues to be the cornerstone of a St. Sebastian’s education today.

During the 2016-2017 academic year, St. Sebastian’s will be celebrating its 75th anniversary and look back at the many extraordinary people and stories that have been a part of this great School.


A Three-Day "Birthday Party"

From September 29 to October 1, St. Sebastian's celebrated its anniversary with a series of special events including Founder's Day, 75th Game Day and the 75th Gala. Check out a recap of our three day birthday party weekend!
