Guinn had an amateur career(record 290-26), twice winning the National Golden Gloves Super Heavyweight Championship in 1997 and 1999 but losing in the Olympic qualification to Calvin Brock. In 1998, Guinn won the U.S. National Championships and won a Bronze Medal at the Goodwill Games in New York City.
