Bob's Purpose:

"I have been training Brazilian Jiu-Jitsu since a young age and I feel blessed for the opportunity that was once given to me. I had great coaches and mentors to guide me through my life, BJJ taught me more than just how to defend myself and be an athlete but also how to have hope when times are hard and that helps me a lot to face the challenges of life. 

I believe BJJ can do the same for every person as I have seen it happening to my students, people start bjj for fitness or self defense and when they notice they have developed confidence, fitness and skills that they would have never imagined when they started their journey.

Teaching BJJ is more than just my work and passion but also my mission in life, to guide and advise people through BJJ, I believe passing on the knowledge is a blessing and I want to help people grow through this amazing art".
