About us 

Overall Brazilian Jiu-Jitsu opened in August 2016 in the heart of Agoura Hills, CA. Home to instructor Nicollas Welker, first degree black belt bring all walks of life to learn the martial art of Brazilian Jiu-Jitsu at his 2,200 square foot facility. 

Agoura Hills was chosen as the prime location for Overall Brazilian Jiu-Jitsu because of its family-oriented community and active lifestyles of its residents. Professor Nicollas aims to create an environment where people find comfort on the mats, can train and get in shape with their families-- not simply get in, and get out.  The goal will always be to make a nurturing environment for learning Brazilian Jiu Jitsu, learning self-defense and getting in great shape. This is the perfect way to describe what Overall BJJ can offer.


The name Overall Brazilian Jiu Jitsu stems from the idea that Jiu-Jitsu should be used as a catalyst for a positive lifestyle. This lifestyle includes getting into shape, being family-oriented, building friendships and bonds, learning self-defense and/or sport Jiu-Jitsu. Overall implies that training here is open for all types of people young and old. And that the Jiu-Jitsu you learn is well-rounded, complete, and whole.

Nicollas Welker is a first degree black belt in Brazilian Jiu Jitsu Originally from Sao Paulo, Brazil, he made the move to the USA in 2013 at 21 years of age with a dream to open an academy of his own in California.


Nicollas began training at the age of 10 but wasn't truly in love with being on the mats until the age of 14 when he entered his first competition and won. From then on, he trained harder for the following tournament. Another gold medal gave him the realization that not only was he capable, but he enjoyed the feeling of training and competing in Brazilian Jiu Jitsu. 


Once he turned 17 and received his blue belt, the opportunity arose to begin teaching beginner jiu jitsu. He spent the next six years in Brazil teaching, training, and competing. Some of his major titles in the lower ranks include: third place Brazilian Nationals purple belt, second place  weight category and third place open class American Nationals brown belt, FBJJ Circuit Paulista champion brown belt, CBJJE Worlds champion brown belt.


Nicollas was promoted to black belt at the age of 22 and was more motivated than ever to make Brazilian Jiu Jitsu his career. Already teaching and training within Ventura County, the dream of owning his own academy was coming more and more into fruition.


He continued competing and accomplished notable titles at the prestigious rank of black belt: IBJJF Houston Open champion, 2x IBJJF San Jose Open champion, NABJJF Worlds champion, IBJJF Atlanta BJJ Pro third place.


Teaching for Nicollas is a passion. He wants to lead his students into a healthy lifestyle and help them accomplish their goals, whatever they might. The Brazilian Jiu-Jitsu classes are taught solely by Nicollas and include techniques, concepts, and mentalities that he has learned over his many years of training. If you compete, he will be right there mat side to lead you to victory and encourage you in defeat.
