In her 40's, Diane went to college and gained a degree as a Paralegal. Her late career was with an international law book publishing firm, Thompson (Law) Publishing,as a Credit Manager. She retired from there. Diane had a life-long love of learning and great friends.  She enjoyed her monthly Club dates with friends during her children's early years. She was a people person and her revolving door was always open to friends, including nuns and priests, of which there were many. She always had to have a phone to hand to the very end. In the earlier days, the cord stretched from room to room. Early multi-tasking!  Her travels with friends and family to Australia, Ireland, Europe and Jamaica as well as PTA, Mothers Club and 30 years at St Andrew's adequately defined her life. She loved her husband and family. They were her greatest joy. She will be missed and loved forever. Services pending. For information please call 847-685-1002 or visit www.cooneyfuneralhome.com
