Master Ketchum started with Judo in 1974, and a year later began Taekwondo with Master Ike Stafford in Springfield, MO. He later earned his 1st gup in Taekwondo and Hapkido under Grandmaster Choon Lee of Lenexa, KS.
In 1985 he attained his Kukkiwon 1st dan while training under Grand Master Sung Dal Cho of Aurora, CO. During this tenure he attained his 3rd dan, competed, and taught as an assistant instructor to Grandmaster Cho for 10 years. He was active refereeing, and leading weekly competition classes to benefit young athletes learning to fight. Here he met the Martinez family.
Grand Master Cho passed in 1994, and the family moved to Evergreen, CO. Master Ketchum suffered a major back injury in 1998 and was away from the art until 2004, where he trained and taught with his friend, Master Tom Spratt of Clear Creek Taekwondo in Evergreen. He became reacquainted with the Martinez family, and discovered Masters Georgie and Steven Martinez had their own school which concentrated on Olympic style sparring, and began training with them in 2006, while still teaching a bit in Evergreen.
Master Ketchum earned his 4th dan in 2009, taught and trained at Martinez Taekwondo until school closure in 2012. He is currently training with Grandmaster Andre’ DeOliveira in Thornton, CO and earned his 5th dan in 2015.
