St. Mary Catholic School is a vital and valued ministry within the evangelizing mission of St. Mary's Parish of Riverside and its neighboring suburbs, and of the global Catholic community. Believing that each student is a child of God, St. Mary School challenges each to achieve academic excellence, to embrace the gospel message, and to make a difference in the world through Christian witness, service, and leadership.
The mission of St. Mary School is to provide the children of St. Mary's parish family with a firm foundation in the Catholic faith, traditions, and moral values; and to prepare them to become well-educated Catholic adults who will provide leadership and service within the church and society in the 21st century.
St. Mary is a very special community in which teachers and administrators are united and work in harmony with parents, who we recognize as the primary educators.
It is a partnership that is dedicated to the full realization of each child`s spiritual, academic, and life skills potential.
At home and at school, together we endeavor to integrate God`s message into the children`s daily activities and encourage them to embrace the meaning of social concern and service to others.
