Mr. Royal

Mr Royal is a red belt in Tang Soo Do and a white belt in Brazilian Jiu Jitsu. He helps assist with the kids classes and trains with the adults.

Royal Harrell was born in Los Angeles, California and moved to Vista at the age of 9 with his mother and younger sister who has cerebral palsy. His family grew up poor, but were rich at heart. Because of his little sister, he later became a substitute teacher for special education. He enjoys helping people with all types of disabilities and would like to one day open a studio for special needs.


Royal is a father of four and two of them train at California Karate Academy -- Kai and Haleigh Harrell. Having his little ones doing what he likes to do and not forcing them to train is, in his words, epic. "Honestly it’s Haleigh that keeps me motivated. She gives me hope and motivation, teaching me the NEVER GIVE UP rule."  


Besides learning Tang Soo Do, Royal has a little background experience in Shotokan, Shorin Ryu and Jiu-Jitsu. Because of his previous and current training he now teaches the sparring classes on Fridays. He thinks that a well-rounded martial artist should train in both stand up and ground disciplines and encourages students to do both.

Our Brazilian Jiu-Jitsu Team

Professor Chris Serrell

A black belt in Brazilian jiu-jitsu, Professor Chris runs our Jiu Jitsu program at Fulcrum BJJ. Students who train in the karate black belt club can train in our Jiu Jitsu program as well.

Program Director - Professor Chris started training Brazilian Jiu Jitsu in November 2005 in Las Vegas, NV with Team Mica (Professor Mica Cipili).  Among some of the important principles of life and Jiu Jitsu, Professor Mica gave him a deep appreciation for the fundamentals and a passion for the art. 

Chris moved to Denver, CO about 2 years later and started training with Colorado Brazilian Jiu Jitsu under Professor Dave Ruiz where he would eventually earn his brown belt.  He learned from many things from Professor Dave, those that stand out most were how to be a good coach and a better listener.

With a move to upstate New York he started training at Renzo Gracie Latham, under Professor Bruno Tostes.  Professor Bruno and the team would end up flying out Professor Dave to NY to award him his Black Belt in Sept 2015.  


Eventually, Chris moved to San Diego, where he trained with the Clark Gracie Team under the watchful eye of Professor Clark Gracie.  Clarks lineage speaks for itself and the level of play at his academies is awe-inspiring.

Chris is excited to be a part of the Brazilian Jiu Jitsu program being offered at California Karate Academy.  Of all the things he has learned over his years of training is that your team can make or break your training. While Jiu Jitsu is an individual pursuit, your training and improvement is equal to what your coaches and teammates bring on a continual basis, and he will give you his best every day that he shares the mat with you.
