Althoff is a diocesan Catholic high school serving students who primarily desire to pursue, in a Catholic environment, a strong academic program that will prepare them for post-secondary education. The school's strength and its future lie in its Catholic heritage, the diverse backgrounds of its students and faculty, and its high academic standards. Through a process of faith formation and challenging educational experiences, faculty and staff strive to empower students not only with academic and technological skills, but also with skills for living.
