Welcome to Saint Mary's High School!

Saint Mary's High School is a Roman Catholic, Diocesan, co-educational high school serving the greater Phoenix area. It is a multicultural, centrally-located school that offers a traditional setting with a primary emphasis on the spiritual, academic, social, and personal growth of each Knight/Lady Knight. Special attention is given to all types of learners with an emphasis placed on students preparing for a college/university post-secondary experience.

Saint Mary’s High School is the oldest Catholic high school in Arizona and has been a part of the greater Phoenix metropolitan area since 1917. Saint Mary’s is Arizona’s first Catholic high school, founded by the Sisters of the Precious Blood. The founders were able to set aside classroom space for 4 boys and 10 girls in Saint Anthony’s Elementary school. This was the beginning of the Saint Mary’s community.

After a series of moves and contributions, the Saint Mary's Campus continues to grow on 3rd Street and Sheridan. The history of Saint Mary's is more than a building, or location downtown. Doctors, engineers, scientists, teachers, and other leaders of our community have come to call Saint Mary's home. A tradition of excellence has been held for over 90 years and continues on.

The staff at Saint Mary’s High School is excited to build upon the rich traditions, the many successes occurring presently, and the rewarding challenges that lie ahead to assist the Knights and Lady Knights of Saint Mary’s with their spiritual, academic, social, and personal growth. My prayers continue to reflect a hope that families will partner with staff members with an energized desire to help each Knight and Lady Knight grow as much as possible. 

On this website, you’ll find information about Saint Mary’s students, faculty, programs and alumi, in addition to opportunities for voluntarism, career networking and parent involvement. Whether you are a prospective Knight or Lady Knight, parent or you are revisiting your alma mater, I hope you’ll consider www.smknights.org as your source for up-to-date information on happenings at Saint Mary's High School.

Sincerely,

Suzanne M. Fessler, Principal
