THE FUTURE IS YOU!

Our mission at Althoff High School is that we are called by Jesus Christ to educate young people, in the Catholic tradition, to lead successful, faith-filled lives. Our vision for generations to come, is that Althoff High School will be a vibrant, Christ-centered community for young men and women. We will be the school of choice for families who know that academic rigor and faith formation in a small, family-like environment, right here in our own community, is what is best for their child. To accomplish this vision and mission, we rely on the support of our community partners, families, and foundations.

Explore the many ways that you can support the students and staff at Althoff Catholic High School to stay spiritually and fiscally strong.

Help support #AlthofCatholic and #GiveSTLday2026 at https://www.althoffcatholic.org/giving/givestl2026.cfm! This year, your #GiveSTL2026 gift will support our Annual Fund, which is used to cover expenses that tuition does not, like updating instructional tools, providing competitive teacher salaries and coveringbuilding maintenance. Because of you, Althoff continues to thrive. Enrollment for 2025–2026 reached a seven-year high, and your support helps us enhance academics, expand programs, improve our campus, and keep Catholic education accessible. You help create an environment where excellence, character, and faith are lived daily. Yet challenges remain. Tuition covers only 65% of the true cost of education, and while parishes help, a gap persists. We rely on your generosity to make faith-based education possible for all families. Every gift to our Annual Fund strengthens the foundation on which our students learn, grow, and live lives of faith, knowledge, and service. Thank you for making our GiveSTL Day 2026 a success!

Please welcome Anna Satterfield to her new role as a dance coach! "I danced at Adams School of Dance for 15 years and still enjoy taking their adult classes in my free time. For the past two years, I have been the French and Consumer Education teacher at Althoff and have loved every moment of being a Crusader. I am excited to begin this new journey with the dance team and look forward to sharing my passion for dance while helping build school spirit, leadership, dance technique, and team pride at Althoff!"
