Affording St. Sebastian’s

The two most important questions you will ask during your admissions search are likely "What is the right school for my son?" and "Can our family afford it?" 

We want to help you answer these important questions. If St. Sebastian’s and its combination of academic rigor and spiritual depth is the best school for your son, we encourage you to apply, regardless of your family's ability to meet the full cost of attendance.
