Rob Wagner has been doing something amazing every month for kids battling cancer.
Known as the Ice Cream Man, he owns a Dairy Queen in Niles and donates 200 sundaes every second Friday of the month to patients at Advocate Children's Hospital's pediatric oncology unit in Park Ridge.
Wagner has been sending sundaes for eight years.
You can see his interview with ABC 7 below as well as some pictures with some of the patients he's visited.
