American Top Team (ATT) is one of the primary teams in mixed martial arts. The gym was founded by Dan Lambert, who brought in former members of Brazilian Top Team , and Ricardo Liborio, but there is no formal affiliation between the two teams. ATT's main academy is in Coconut Creek, Florida, and there are affiliated academies throughout the United States. ATT features professional fighters who have competed in many major promotions, such as the Ultimate Fighting Championship (UFC), PRIDE Fighting Championships, DREAM, K-1, Strikeforce, Bellator and Professional Fighters League (PFL).
