Dan Dinh entered the League of Legends competitive scene by forming All or Nothing with his brother, Andy "Reginald" Dinh. Despite early success, he left the team after he and his brother made conflicting calls in game. Dan then went on to create the team Epik Gamer in 2010, where he played as their jungler. He left the team in March 2012 and joined 4Nothing. After leaving 4Nothing in April to be replaced by ClakeyD, Dan Dinh announced his retirement and temporarily became a caster for various events. In December 2012, Dan reformed Epik Gamer for the January Season 3 North American Qualifiers, but disbanded after being eliminated in the group stage. Later that month, Dan Dinh moved in with Team Solo Mid as a substitute jungler during Season 3, though he saw no play time at major tournaments. Dan Dinh left his position on TSM in October 2013 and moved to Los Angeles to coach Cloud 9.
