St. John XXIII Catholic School is able to offer several family events (Fall Spooktacular, Mother/Son Bowling, Father/Daughter Bowling, Breakfast for Baby Jesus, etc.) because of our dedicated parent base. SJ23 parents, in conjunction with parish and alumni volunteers, organize and run all of our school fundraising events that are so vital to a thriving school environment.

Funds raised from these programs help offset operating expenses, keep tuition rates manageable, and support our wonderful student, faculty, and family programs.

Consider volunteering and sharing your talents and make some great friends along the way. Every family is asked to volunteer throughout the school year and support our fundraising programs. Volunteerism is the heart of our vibrant and enthusiastic family community. We appreciate the time and efforts of our parent, parish, and alumni volunteers! The Home and School Association meets once a month. All parents are invited to attend.

Become a Volunteer Today.

The Key Event continues to be the main source of fundraising for St. John XXIII Catholic School, and your generosity allows us to instill and provide exceptional academics, quality faith-based education, and service to our students. This yearly auction is the result of many hours, patience and tremendous commitment of the St. John XXIII community. Without the support of willing volunteers, faculty, alumni, friends of the school, sponsors, parents and students, the event would not be possible. Thank you for your continued support.

Everyone here at St. John XXIII Catholic School would like to sincerely THANK YOU for your involvement in the 2022 Key Event – Through the Decades. With your help, the event raised $90,000. Without the support and generosity we received from our school families, friends, faculty, staff, parish members, community partners, and local businesses, this would not have been possible. We are looking forward to our continued partnership and success in the years to come.
