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.

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 708-579-2333. Thank you.
