Our Mission :

The purpose of St. Mary’s High School is to educate students to be successful in all relationships.
Each St. Mary's High School graduate is prepared with the background and skills to be a faithful disciple of Christ, a productive learner, an effective communicator, and a responsible citizen.

Our Philosophy :

As a community, we believe man has a responsibility to his fellow man; that in realizing and accepting our talents and limitations, we are able to work together in a loving and giving community to bring a fuller and richer meaning to life.
As an educational community, we believe that each individual is a unique and valuable person who learns through his/her experiences. We are capable of providing experiences that will help each individual know and reach toward his/her potential. Interpersonal contact both in and out of the classroom is a major and critical part of the teaching experience.
As a Christian educational community, we accept and emphasize the Catholic faith. We believe that each person is created by God to honor and serve Him. We believe that Jesus’ message is to love. Guided by the Holy Spirit, we accept the call to live and teach as Jesus did.

Diversity Statement :

Recognizing that our differences give us opportunities for understanding, St. Mary's High School strives to promote respect, acceptance, and sensitivity to all.
Since a component of a quality education is to prepare students for the multicultural world in which they live, we encourage each other to value alternative viewpoints and be sensitive to the life experiences, feelings, hopes, and challenges of others. It is our intention to empower individuals and discourage stereotypes and prejudices.
We believe that our commitment to diversity is an ongoing process dedicated to achieving fairness and justice in our school community.
