Personal
Quincey hails from Orangeville, Ontario, and cites former Toronto Maple Leafs forward Bill Berg as one of his childhood idols. "When I was young, my dad took me to see a Kings game in Toronto. I was watching Wayne Gretzky, but my dad said to me, ‘watch the way Bill Berg plays. Look at him working in the corners, not being afraid to get his nose dirty, and doing all of the little things.’ Berg became one of my favorite players to watch after that because of the effort he put, and how he never took a night off. I feel like I have taken a similar approach to working hard and being confident to do whatever is asked of me." Kyle celebrated his day with the Stanley Cup from the Detroit Red Wings in Caledon, Ontario, with family and friends. He also took the Cup to Alder Street Recreation Centre for autographs and pictures with local fans. Kyle is married to longtime girlfriend Rachel Quincey. The couple wed on 5 February 2016 before the Hon. Stephen J. Murphy, III, United States District Judge.
