Welcome to St. Mary Immaculate School!

Greetings and welcome to St. Mary Immaculate School, the home of the Spartans!  I am thrilled that you have decided to view our school's website in order to learn more about the wonderful students, staff, and programs we have to offer.  St. Mary's has a reputation of excellence and we will continue to strive to become the best.

At the heart of what we do is faith formation.  We have an all school Morning Prayer, daily religion classes, and join our parish priests to celebrate Mass weekly.  Our students learn to cherish and live Christian values today and always.  In addition to this strong foundation in Catholic Values, our quality academics allow us to develop the whole child so they will be responsible members of their church, community, and country, 

Our students are challenged to use their God-given talents to fulfill their potential as they learn and grow closer to Christ each day.  We follow the academic standards in the curriculum set forth by the Diocese of Joliet.   We recognize the need for a comprehensive, well-rounded curriculum to guide each child to live out their potential.  Therefore, we also offer a variety of curricular content and enrichment such as music, band, Study Skills, PE, STEM, art and Genius Hour.

After visiting our website, I invite you to visit our school and see just how exceptional you will find our school and staff.  Each child is important and every family is valued.


Jennifer Errthum, Principal
