The best way to experience the mission of St. Sebastian's is by visiting our campus in person. In the meantime, here is a glimpse of life on Greendale Avenue, from the classroom to the chapel, in the library, and on the fields.

Why St. Sebastian's?
St. Sebastian’s is a truly special place. From inside the classroom, to the athletic fields and into the art studio, everybody here has been so supportive of everything that I have desired.
