Why St. John XXIII Catholic School?

Check us out on Facebook!

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.

Looking for a meaningful way to make a difference? Come join the St. John XXIII Catholic School family as a substitute teacher! Whether you’re looking for occasional work or simply want to give back to your community, substitute teaching is a wonderful way to support our students, teachers, and ...mission.

To become a substitute, you’ll need to:
✅ Hold a bachelor’s degree (in any field—an education degree is a plus!)
✅ Complete the Archdiocese of Milwaukee employment application:
https://www.archmil.org/Resources/Application-for-Employment-Teachers-Principals.htm
✅ Complete Safe Environment requirements, including the background check, Code of Ethics, and Social Media & Digital Communication Policy:

Once these steps are complete, we’ll invite you to visit our school and meet with our Principal. We’d love to welcome you into our school community! If you’ve ever considered working with children in a faith-filled environment, this is a great opportunity. Please share this post with friends or family who may be interested!

Summer Family Service Challenge: Go Make a Difference This Summer!

Making a difference doesn't always require grand gestures. Sometimes the greatest impact comes through simple acts of love and service. This week, choose one act of service to do as a family:

✅ Write a ...thank-you note
✅ Help a neighbor
✅ Donate food or clothing
