Phenomenal school, outstanding leadership, devoted teachers who love their jobs, dedicated coaches who care about their players and success, where faith is inspired, nurtured, celebrated and academic excellence is the assumption. Friendships that will last a lifetime. Could not possibly have dreamed of a better 4 years for my daughter.

The best decision we have made was sending our daughter to Kellenberg Memorial High School. Both my husband and I attended parochial school, but our experience can't be compared to what our daughter has experienced. During the last three years, I have witnessed her spiritual growth; her sincere desire to help those less fortunate; to her academic focus. In a few months, our son will be joining the Kellenberg family, and we're confident he will be just as successful.

An incredible school, that our two sons thrived at, so differently, in academics, spirituality, sports, and sense of self, independence.. As a friend once said, Kellenberg is like having an extra parent in the family.. In a good way. During the most turbulent years of development, Kellenberg teachers are there, every day, for the students.

Three of my sons and my grandchild attended Kellenberg and I could not be more pleased with the education they got. They are all excellent writers and that has helped them excel in what they chosen to do. I love to still be part of the Kellenberg Memorial HS as part of KAPA, the school has been part of my family for the past twenty one years. I would recommend Kellenberg to any parent.​

The kids are always so happy! They are always going from one club to the next activity and it’s hard to get them to leave school. They get a strenuous and rigorous, classic education that is tailored to the needs of students.

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.
