OUR COMMUNITY
“The time and devotion given to every student by every teacher is incredible to say the least.”
“Once in. Never Out. It’s resoundingly true. Alums are always coming back as though they never left.”
“St. Sebastian’s is more than a school or a community. It is a family.”
Why St. Sebastian’s?
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.
