    Crusaders, Come Home! It’s time for a homecoming like no other.

    Our Honorary Chair, Coach Glenn Schott, and Althoff Catholic High School invite you to join together as one united Class of Crusaders in celebration of Althoff’s enduring legacy.

    Join us as we embody our cherished motto, "Once a Crusader, Always a Crusader." Together, we’ll honor the legacy, the leaders, and the lasting future of Althoff. From the very first graduates to this year’s senior class, let’s gather to ensure Althoff’s vibrancy for the next 60 years and beyond.
