The flagship fundraising event for Althoff Catholic High School, the "Denim and Diamonds" annual gala and auction is vital in supporting Althoff Catholic High School's mission by providing funding for scholarships and tuition assistance, operations expenses, technology and learning aids, building and grounds upgrades and maintenance, educator salaries and more.
Your support helps bridge the gap between tuition and the true cost of education, ensuring that a superior Catholic education remains affordable for all.
Rooted in Jesus Christ and Catholic values, our focus on character development and Catholic values remains a defining strength. We continue to educate the whole child (mind, body and spirit) so our students are both academically prepared and grounded in faith. Thank you for joining us in this important mission through your generous support of the "Denim and Diamonds" Gala and Auction!
