NAGA

From OTMWiki

Pretty much the premier grappling circuit in the US. Travels all over the country putting on tournaments year round. Also does some MMA promotion, but the bulk of their business is grappling tournaments. Divisions are usually done by weight, age, and experience. Fairly well organized, but draws such a large crowd that the one day tournaments usually last all day and well into the night. Staff is usually pretty friendly and cooperative and you are allowed to compete in multiple divisions for the same price unless you are fighting for prize money in the pro division. Organized by Kipp Kollar, a very friendly guy with a passion for the sport.
