St. Mary Of Gostyn Catholic School (Top Ranked Private School for 2025-26)

440 Prairie Ave
Downers Grove, IL 60515

St. Mary of Gostyn School is a Catholic faith community called together by God to educate children, to proclaim the Good News, and to translate this proclamation into action.

The faculty, staff, and parents form a unique partnership in carrying out this mission of teaching the message of Jesus by celebrating meaningful liturgies, providing opportunities for service within the community, and passing on the beliefs and traditions of our faith.

This community provides witness to Jesus Christ, proclaims the Gospel values by living the Christian message, and helps to build a faith that will lead to a commitment to all people.

Realizing that we serve a diverse community and that each child is unique, it is imperative that we discover the abilities, talents, and needs of each child and do our best to create, in partnership with the parents, an environment that responds to these needs.

Religious education, including various opportunities for worship, is a priority in our school.

We believe that other opportunities for growth in self esteem, happiness, and the curriculum subjects are essential.

These opportunities include academic excellence, building personal relationships, and service to others as exemplified in the message of Jesus.
