About SJ23
Why The Key Event Matters
At St. John XXIII Catholic School (SJ23), we’re committed to providing a strong foundation of Catholic values, academic excellence, and whole-child development for students in preschool through 8th grade. Our dedicated faculty and staff foster academic, social, emotional, and spiritual growth—guiding every child to reach their full potential and live a life of purpose, faith, and service.
The Key Event is SJ23’s largest annual fundraiser and a vital part of ensuring we continue to offer outstanding, faith-based education.
Now in its 27th year, this event is a celebration of the generosity, passion, and commitment of our school community—parents, alumni, volunteers, parish members, faculty, friends, and sponsors—who make our mission possible.
