A bobsledder, Kirby earned a bronze medal in the four-man event at the 1993 FIBT World Championships in Igls, Austria.
This accomplishment marked Kirby as one of the first United States Bobsled athletes to medal in a World Championships in 28 years.
Kirby picked up five U.S. National Push Championships on his way to competing in two Winter Olympics – Albertville in 1992 and Lillehammer in 1994.
Following stints working in television and insurance, Kirby later became an adjunct professor at William Penn University.
In his spare time, Kirby is a community activist volunteering for Special Olympics Iowa, the American Red Cross, and the local food pantry.
