Career
Mulkey began practicing Muay Thai in his 20s under Saekson Janjira at Janjira Muay Thai in Dallas, Texas. After training there for six months, he moved to Las Vegas, Nevada. He turned professional in 2009 after an undefeated amateur career.
On August 28, 2010, Mulkey lost via unanimous decision to Remy Bonnel in Primm, Nevada.
He then lost to Joe Schilling by second round technical knockout in Los Angeles, California on December 5, 2012 in a WBC Muaythai United States Super Muddleweight (-76 kg/168 lb) title eliminator. He snapped a two-fight losing streak by defeating Douglas Edwards by TKO in round two in a rematch in Primm, Nevada on February 12, 2011.
This was followed up with two back-to back wins in the space of a month in May 2011 when he beat Ken Tran by unanimous decision in Primm and Phillip Sidkrunoom by TKO due to low kicks in Thailand. He made the first defence of his title against Simon Chu in Las Vegas on November 19, 2011, taking a unanimous decision over the Englishman.
He then went up against Gregory Choplin in Las Vegas on May 14, 2012.
He was slated to face Saiyok Pumpanmuang at Thai Fight: Pattaya in Pattaya, Thailand on April 17, 2012 but instead faced Bernueng TopKing Boxing and lost a decision after three rounds. In March 2012, it was reported that Mulkey had signed with Glory, one of the world"s premier kickboxing organizations, to compete in the 2012 Middleweight Slam tournament. He was replaced by Michael Chase Corley, however, as America"s second representative alongside Kentucky Hollenbeck.
He joined K-1 instead and debuted against Kit Cope at the K-1 World Grand Prix 2012 in Los Angeles on September 8, 2012.
