Professor Sergio Castillo, or known as “Spidey” as nicknamed by his professor, started training jiu jitsu at age 17 under Professor Erwin López at the original Tri Town location in Frederick, CO in August of 2005. Six months after training every day and quickly learning everything he could, Sergio began competing in local grappling tournaments. Testing his skill set further, Sergio ended up taking 1st place at the prestigious IBJJF Pans tournament in 2007 as a blue belt in the rooster weight division and later placing 3rd at the IBJJF Worlds that same year.
Sergio turned his attention to his collegiate studies but continued intensively training and was promoted to black belt by Professor Erwin López in July of 2013. In 2014, Sergio became a police officer in the Denver metro area and has since served in the capacities of a field training officer, SWAT operator, and most importantly a defensive tactics/arrest control instructor. Becoming a police officer helped Sergio expand his understanding of Jiu Jitsu and it’s vital importance for self defense in close quarters.
Sergio’s favorite aspects of BJJ is teaching the art’s effectiveness for real world applications and the opportunity for 100% live sparring, which leads to learning the ability to keep calm, collected, and overcome highly stressful and fluid physical confrontations.
