Giving
Support Riordan – Invest in the Future of Our Crusaders
At Archbishop Riordan High School, giving is more than a donation—it’s an act of faith in the potential of young men and women shaped by the Marianist values of faith, service, family spirit, and inclusivity.
Your support helps us provide a transformative Catholic education rooted in academic excellence, personal growth, and leadership development. Every gift—large or small—directly impacts the student experience, ensuring access to meaningful programs in the arts, academics, athletics, sciences, and campus ministry.
Whether you are an alumnus paying it forward, a parent contributing to your child’s journey, or a friend who believes in our mission, we invite you to partner with us. Together, we can continue to build a strong foundation for today’s Crusaders and tomorrow’s leaders.
Join us in making a difference. Because at Riordan, giving is part of what makes us a family.
