Andrew Moskowitz

AndrewAndrew Moskowitz grew up in a small beach town in New York and earned his BA in Psychology at the University of Miami in Florida in 2010. His first experience with Brazilian Jiu Jitsu was when a college friend asked him to go to a class at a local gym.  Since the Jiu Jitsu guys seemed like such a tight knit group, he started to go to more classes to make even more friends. Andrew’s favorite part of training is that every situation is different and no matter who is on the other side, there is always something new to learn. Some of his proudest accomplishments include obtaining his purple belt in Brazilian Jiu Jitsu and beginning his Ph.D. in Quantitative Psychology at UCLA. He is looking forward to continuing his training and to one day become both a Black Belt and University Professor.
