Dean, who was graduating high school, made his senior freestyle debut on May of 2013, when he went on to place third at the Northeastern Regionals and sixth at the US University Nationals. At the 2015 Pan American Championships, Dean made his Greco-Roman debut with no previous training in the discipline, and went on to place second. In April 2017, Dean decided to wrestle at the US Open in freestyle, and went on to place sixth. Afterwards, he placed third at the Pan American Championships, with technical falls over former Olympian from Colombia Carlos Izquierdo and South American Games runner–up from Peru Pool Ambrocio. Dean then announced he would try his hand as a Greco–Roman wrestler, but after competing and losing in his first match at the 2017 US U23 World Team Trials, he decided to retire.
