It’s hard to talk about our Judo and BJJ instructors without sounding like we’re bragging. The plain fact of the matter is that we have one of the best teams of martial arts instructors you will find anywhere. Led by 4X Judo Olympian Brian Olson, our instructors are talented, accomplished, passionate and the kind of people you just enjoy hanging out with, because after all, although we take what we do very seriously, Judo and Brazilian Jiu-Jitsu is supposed to be fun.
