Welcome to Saint Mary School


As principal, it is my privilege to welcome you to the school family of Saint Mary Parish, a school which prides itself on a tradition of excellence since 1855. We are a warm and welcoming community where a highly qualified faculty and staff create an atmosphere of mutual respect, cultivating social and emotional learning along with Catholic faith formation and academic excellence. Our mission statement “Saint Mary School is a community where our children develop the courage to act on their Catholic beliefs and demonstrate the highest levels of academic excellence and service through Jesus” is the foundation for our daily activities. 

While parents serve as the primary educators of their children, faculty and staff of Saint Mary School offer their partnership and expertise in a variety of areas to continue the development of the whole student; spiritually, academically and socially. We value the importance of working collaboratively to prepare the students in our care for their success now and in their futures.  We meet our goals through a recognized program of academic excellence which challenges our students to academic benchmarks aligned with the common core standards and the curriculum standards of the Archdiocese of Chicago. 

Leadership development is also recognized as a priority in helping our students reach their potential. This goal is supported by the research which indicates that leadership can be taught and learned. Direct instruction, service opportunities and requirements, an emphasis on personal responsibility and mutual respect, and social development via extracurricular activities such as Student Council and sports programs are all vehicles to building this skill. 

Our community is made strong by the Catholic environment which is integrated throughout our program and easily visible in the Saint Mary’s experience which includes liturgical celebrations, community prayer, religious study, opportunities and requirements for service, sacramental preparation and an emphasis on moral decision making. Students are influenced by the visible presence of Fr. Dan Whiteside, in addition to the faculty and staff, each of whom give testimony to faith in action. In these experiences our students are preparing for their role as messengers for sharing the good news of Jesus Christ.
