Campus Ministry
“Prayer is the raising of the mind to God. The actual words matter less.”
~Pope St. John XXIII
Our dynamic Campus Ministry program is committed to playing a vital role in forming the hearts and minds of our students by providing opportunities to encounter Christ through the Liturgy, our Retreat Program, and our Works of Mercy program. Housed in the Center for New Evangelization, Campus Ministry will assist our Theology Department in fostering a love for Christ and an identity rooted in Him.

Student Life
At St. John XXIII, we believe that the formation of our students takes place not only in the classroom but also through participation in extracurricular and co-curricular activities.
We believe that the formation of our students takes place not only in the classroom, but also through participation in extracurricular and co-curricular activities. With 20 clubs, five national honor societies, three student organizations, four performing arts, and 20 athletic opportunities, students have the opportunity to join many clubs and participate in a variety of activities to enhance their high school experience. We also offer nearly two dozen 18 AP, Pre-AP, and honors courses to challenge and inspire.
