  DJ Castillo   DJ was born and raised here in the South Bay and grew up playing baseball. DJ's brother introduced him to CrossFit at the 24 hour fitness in Hawthorne and he quickly became “that guy” who did CrossFit at globo gyms.  While attending UC Riverside, DJ continued pursuing CrossFit and became known as the "YouTube Kid" because he learned most of his movements from online videos.  After his freshman year at UCR, DJ needed to find a CrossFit box for the summer. Crossfit 310 was the first gym to pop up on google and he immediately fell in love with the place and the culture it holds. DJ loves helping athletes move better, increasing their quality of life, and connecting with them on a deeper level that goes beyond CrossFit. In December 2017 DJ received his Crossfit Level 1 certification and we love having him as part of the team!
