Mike was born in Peoria on June 30, 1952 to Mildred (Slonneger) and Ronald Duncan. Mike graduated from Peoria Central High School where he played football and met his wife of 47 years, Robbie (Geddes). Together they had two wonderful children, Andy and Jolie. Mike worked at Caterpillar for 37 years and retired in 2012 as an engineering team leader. He loved his work. In his retirement, he enjoyed spending a month each winter with Robbie in South Carolina and adored his three grandchildren, Vivi (6), Luca (3) and Nash (2). Outside of spending time with family, Mike was an avid lover of politics and was always up for a friendly debate. He was a loyal fan of the Chicago Cubs since childhood and was always ready to root for the underdog. On the weekends, you would often find him watching the Fighting Illini, Chicago Bears or his beloved Cubbies. Mike was also a devoted community member and a mentor to others, active as an usher and trustee at the First English Lutheran Church as well as a board member of the Cress Creek Homeowners Association.
