Daniel Joseph Dillon, Jr., 71, passed away December 5, 2024. Beloved husband of Julie Rosenfeld Dillon, loving father of Rose Adele Dillon and Thomas Milton Dillon, dear brother-in-law, uncle, and cousin to many. Born and raised on the South Side of Chicago, Dan was a lifelong Sox fan, proud of his Irish heritage and Catholic education. Dan taught at Jamieson Elementary School for 27 years. Hosting spelling bees and preparing for holiday assemblies were two of his favorite activities. He was an avid golfer (an understatement), and loved St. Patrick's Day parties, Christmas, and smoking turkeys in the backyard. Dan loved music, especially live performances from opera to rock and everything in between. Julie, Rose, and Tom are grateful for the support of wonderful neighbors, friends, family, caregivers, and co-workers during his battle with vascular dementia. In lieu of flowers, please consider donating to your favorite children's charity. Visitation on Thursday, December 12, from 4:00 pm until the time of the funeral service at 7:30 pm at Cooney Funeral Home, 625 Busse Highway, Park Ridge. For information please call 847-685-1002 or visit www.cooneyfuneralhome.com
