Faith is a primary aspect of the Kellenberg Memorial school community.

A Marianist Education

In addition to the academic and extracurricular programs at Kellenberg Memorial, students also share in a faith experience within the context of a Catholic school community. All activities, both inside and outside of the classroom, are carried out in the spirit of the Gospel of Jesus Christ. Through the spiritual dimension of their education students grow into mature, Christian men and women. Retreat Programs are held in Emmanuel Retreat House on campus and at Founder’s Hollow, a Marianist Retreat Facility in upstate New York.
