We had a festive, ribbon cutting ceremony officiated by Mayor Hoefert to officially mark the opening of our new, turf play surface. A heartfelt thank you to the Mt. Prospect community for all the outpouring of support and generous donations. We are so grateful to our St Mark families and individual and corporate sponsors, without whom this would not have been possible. Please see list of corporate sponsors below and in quick links.
