Student Life
Our mission at SJ23 is not only to foster the academic success of our students, but also to nurture lifelong Catholic values that build strong character and meaningful relationship with God. In partnership with our families and the Catholic Church, we strive to guide each child as he or she grows and matures in knowledge and faith. Students develop a deep appreciation of the liturgy through active weekly Mass participation and through daily religious instruction, reflection, and prayer. SJ23 students further their spiritual journey by preparing for and receiving the sacrament of first holy Communion and reconciliation. Outside the classroom, students focus on individual and communal spiritual growth through retreats and service.
SJ23 offers many co-curricular and student life enrichment programs in addition to its outstanding core curriculum.

Technology & Innovation
In the realm of education, the infusion of technology seamlessly enhances both traditional and hands-on teaching methodologies, fostering a more enriching educational journey for our students. The incorporation of a diverse range of contemporary digital tools not only complements conventional approaches but also nurtures the cultivation of digital citizens. Within a Catholic context, this integration holds a unique significance, emphasizing the responsibility of students to navigate the digital landscape in alignment with moral values. By embracing technology, we empower our students to develop into conscientious digital citizens, equipped with the skills to thrive in our interconnected world while upholding Catholic principles. Our integrated, hands-on curriculum based on Science, Technology, Engineering, Art, and Math (STEAM) engages students of all academic levels. It promotes a deeper understanding of real-world concepts and helps students to become critical thinkers, thoughtful listeners, and effective speakers. In addition to the regular curriculum, middle-school students have electives in the areas of Visual Arts, Coding, Forensics, Extended Enrichment, and more! A student-centered environment dedicated to a deeper understanding of real-world concepts and their relationship to each other. It provides a collaborative meeting space with a multi-media area and includes flexible seating and 3D Printers.

We are so incredibly blessed to have the Skinkis family as part of our St. John XXIII Catholic School community. Now it's our turn to surround them with the love, prayers, and support that make our school family so special.
Join us on Friday, August 14, from 6:00–9:00 PM at Belgium ...Community Park for Belgium Summer Nights Live, a special benefit for William.
William is living with Spinal Muscular Atrophy (SMA), a rare progressive neuromuscular disease that affects the nerve cells responsible for controlling muscles. Over time, it can make everyday activities like walking, standing, swallowing, and even breathing increasingly difficult. Ongoing medical care and intensive physical therapy are essential to helping William stay as strong and independent as possible.
Come enjoy an evening filled with bucket raffles, live music by The Shad Lads, food, beer & wine, Kickball, and a Kids' Zone featuring a bounce house. Please note: This is a cash-only event, and 100% of the proceeds will help support William's medical expenses and physical therapy intensives. Every meal purchased, raffle ticket entered, and dollar donated makes a difference. We hope to see many of our St. John XXIII families there as we come together to support one of our own.

At St. John XXIII, we believe our school is strongest when families and staff work together to support our students. As we continue to grow and strengthen our school community, we are excited to share an important update. Beginning this school year, our Parent Teacher Organization (PTO) will become... the School Community Council (SCC).
While the name is changing, our mission remains the same: to bring families together in support of our students, teachers, and school community. We chose the name School Community Council because it better reflects who we are and how we work together. The SCC is a school-led volunteer organization that strengthens the partnership between families, staff, and school leadership. Together, we will continue to plan events, support school initiatives, organize fundraising efforts, and create meaningful experiences that enrich the lives of our students.
This change also allows us to streamline communication and planning while ensuring that our volunteer efforts align with the goals and priorities of St. John XXIII. Most importantly, it creates an inclusive opportunity for every family to be involved—whether you have an hour to volunteer at an event, help behind the scenes, or serve on a planning committee.
Our new tagline says it best: Working Together for Every Student.
We are incredibly grateful for the dedication of our PTO volunteers over the years. Their time, talent, and generosity have helped build the strong community we enjoy today, and we look forward to continuing that tradition through the School Community Council.
At our Back to School Night, you'll receive more information about upcoming events, volunteer opportunities, and ways to get involved. We hope you'll consider joining us as we continue building a welcoming, faith-filled community where every student can thrive. Thank you for your continued support of St. John XXIII. We look forward to partnering with you throughout another wonderful school year.
