The mission of Saint Mary's Catholic High School is to provide a liberal arts education that forms virtuous young men and women to know the truth and love the good.
Saint Mary's High School is a Roman Catholic, diocesan, coeducational high school serving the greater Phoenix area.
It is a multicultural, centrally located school that offers a traditional academic curriculum with a primary emphasis on college preparation. As a Catholic school, Saint Mary's has the unique privilege and responsibility of providing spiritual resources for the school community.
We believe that by promoting moral values, fostering lifelong service, instilling knowledge of the truths of the Catholic faith, and integrating that faith with all that is taught and experienced at Saint Mary's, students are provided with a solid foundation on which to live out their faith in our world. Additionally, we strive to provide an environment in which students can become contributing members of their faith communities.
We strive to leave lasting impressions of the values of honesty, decency, and integrity with our students.
Because each student must be able to make informed decisions and to live according to Christian principals, we encourage self-discipline, self-respect, respect for others, and growth in learning so that students will be able to deal with everyday issues.
