WELCOME TO
St. John XXIII Catholic School
St. John XXIII Catholic School (SJ23) provides a foundation of Catholic values and academic excellence for its students in preschool through 8th grade. Our faculty and staff are dedicated to building a strong academic, social, emotional, and spiritual foundation for our students.
A Destination to Serve. Learn. Love. Lead.…as Disciples of Christ.
Our theme this year is, “We Were Made to Thrive,” which resonates deeply with our mission and the inspiring legacy of our model saint, Pope John Paul II. Inspired by Pope John Paul II’s unwavering faith and leadership, let us embrace this new year with enthusiasm and a renewed sense of purpose.
“I am beyond grateful for what St. John XXIII and the entire staff has done for my family. My kids would not be in the places they are if it weren’t for the dedication and love of the teachers and staff. THANK YOU ALL.”
