Although I never met Christopher personally, I had the privilege of working for and with his father Dennis while at Exelon. Dennis shared many stories of his family, of his bride Dawn and children. He was so proud of all his children and spoke of Christopher often as well. My prayers go out to the Hieggelke Family. Have comfort in knowing Christopher is flying high with his father Dennis, watching over you all. Sending healing prayers, Darlene Zawojski, Exelon
