I went to a seminar by Wellington "Megaton" Dias at McVicker's Martial Arts Academy this evening. It was very informative. Mr. Dias was sure to attend to every participant--I am quite new to BJJ and he frequently and patiently helped me. He offered both gi and no-gi, sport and fighting advice on most techniques. I came away with some good techniques and a new perspective. Mr. Dias is also giving a two-day seminar in Urbana-Champaign, IL this weekend.
