Stopped in here during a trip to Vegas during an open mat on the advice of a friend who trains there. The competition was FIERCE, the rounds were long, but it was a great workout and everyone was very welcoming. It was an open mat so Sergio didn't have to be there, but he was, spending time and talking with his students (and even me). Crazy to see his red belt just hanging up in the locker room. If you're thinking about BJJ and live in/around Vegas, you'll be hard pressed to find a more focused, traditional BJJ school. Lots of talent here.
