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.

Attention families! Your schedules for the upcoming school year are available to view in FACTS. Please take a moment to log in and review your schedule. Also, make sure to read through the email you received with detailed directions on how to request any changes. If a change is needed based on the guidelines provided through email, please complete the Google Form linked below: Google Form Link: https://forms.gle/reP6WPDfxLppVBA69 Counselors will process requests as they come in and as spots open up in waitlisted courses. Because this process takes time, we kindly ask that you do not email to ask if your schedule request has been finished. Individual emails slow down the overall scheduling process for everyone. tmobile #entry #fn5gl #crusaders
