Committee Chair Sign-Up for Next School Year

We have until the end of the school year to fill the remaining committee Chair/Co-Chair positions. Previous chairs will transition the project to you and the PTC Board VP overseeing your project will support you. It’s a great way to meet other Cossitt parents and get more involved with PTC. Thanks for considering! 

Sign up HERE.

Notes to Cossitt Office
When sending to school with your student notes or forms to go to the Cossitt office, please label the envelope with what the enclosed is in reference to (ex: Book Club, Art Club, Yearbook, etc) so that it can be properly routed. This would be a great help to the office staff and much appreciated. Thank you.
Cossitt Property Watch
Please help us protect Cossitt’s property after hours. If you see inappropriate or suspicious activity after school hours, please call the La Grange Police at the non-emergency phone number of 708-579-2333. Thank you.
Corporate Matching
Did you know that Cossitt PTC is a registered 501(c)(3) nonprofit organization? This means many employers will match employee contributions to nonprofit organizations – like the PTC! So check your personnel manuals or talk to human resources today to see if your company offers a matching gift program. Please contact the PTC Treasurer for more information at cossittptctreasurer @
