St. Mary Elementary School

We are committed to creating a Christian atmosphere for students, families and educators who share a common vision of integrating quality academic standards in an enriching learning environment supported by the Catholic values found in the Gospel message of Jesus Christ.
St. Mary School is a faith community consisting of clergy, principal, faculty, staff, parents and students.
We base our philosophy of education on Christ as our model, through studying scripture and fostering the teachings and traditions of the Catholic Church.
Our major emphasis is on the development of Christian life and the formation of spiritual and moral beliefs of the individuals.
We believe that Catholic education is responsive to the uniqueness of each individual.
It guides all students in the fulfillment of their potential by addressing the needs of the whole child: spiritual, academic, social, physical and cultural.
At St. Mary School, we foster a sense of self-worth, dignity in each individual and an acceptance of others as reflecting Christ.
As Catholic educators, we prepare students to be Christian witnesses by putting their faith into action and we encourage them to be catalysts of change for the betterment of society.
