Excellence Since 1964
Welcome to Althoff Catholic. Since 1964, Althoff Catholic has been shaping young minds and hearts in a supportive, family-like environment. Here, students discover their talents, grow their passions, and develop as whole individuals—body, mind, and soul.
Althoff Catholic High School admits students of any race, color, national, or ethnic origin to all the rights, privileges, programs, and activities generally accorded or made available to students at the school. It does not discriminate on the basis of race, color, national, or ethnic origin in administration of its educational policies, admissions policies, scholarship and loan programs, and athletic and other school-administered programs.
