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.
