Althoff Catholic High School
today
This year we are excited to introduce a new awards ceremony that will honor supporters, alumni, and current students. Legacy and Light, The Crusader Spirit Awards Ceremony, allows us to honor the legacy that guides us and the light that leads us forward. The ceremony will take place on April 26 at 2:00 p.m. at Heritage Hall. Nominations are due by April 14 and can be submitted via the Althoff Website by clicking the Alumni tab and then the Hall of Inspiration tab. Distinguished Alumni Award will recognize the accomplishments of an Althoff Catholic High School or Associate alumnus whose exceptional achievements in their faith, profession, and community have had a profound and lasting impact. Rising Star Award will recognize the accomplishments of a recent graduate (within the past 15 years) of Althoff Catholic High School. Crusader Spirit & Excellence Award will recognize a friend of Althoff Catholic High School who has enriched the Crusader mission through their volunteerism and continuously shows outstanding enthusiasm, loyalty, and pride of ACHS. Salute to Catholic Education Award will recognize a Catholic educator who has dedicated their life to educating young people in the Catholic tradition to lead successful, faith-filled lives.
