Mixed martial arts career

Early career
Castillo began training MMA when he joined the wrestling team at his high school in suburban Sacramento. His vice principal, who was also the wrestling coach, told Castillo that if he joined the team, he would not call his mother after seeing Castillo constantly in trouble. Castillo claims he was scared his first day at practice, "I got the [expletive] kicked out of me that day, but after that, I wasn't nervous at wrestling practice ever." After leaving private school, Castillo graduated from Laguna Creek High School (Elk Grove, CA) and attended Menlo College; becoming an NAIA All American in 2004. His nickname "Last Call" was given to him in college due to his ability perform well in his team's offseason morning runs despite having been up consuming massive amounts of alcohol until last call.

He made his professional debut in November 2007, fighting twice in the month, winning both fights via first round submission. After going 3-0, Castillo signed to fight on the Palace Fighting Championship's seventh card. He fought Andy Salazar winning via submission due to his tough ground and pound.

He won his fifth straight fight after defeating Strikeforce veteran, Isaiah Hill. With the win, Castillo was signed with the WEC.
