School Reviews

I love working at this school and have been employed here since 1987. The Catholic Faith is lived, practiced and taught with joy at St. Mary's. As a Phi Beta Kappa University of Iowa grad, I wasn't sure if this institution would become a 'home' for me. However, I have been challenged intellectually and professionally by my peers and the students, and have been able to use my skills to teach and inspire and to be taught and inspired. All students who can function at a basic academic level can learn in this school's environment.
