Well, technically that's a nickname bestowed upon Mike Constantino by UFC welterweight Charlie 'The Spaniard' Brenneman, who calls him that because he acts as both lead trainer and manager for his fighters.
Mike Constantino is the leader of AMA Fight Club and also manages many of the UFC's top fighters including Brenneman and the brother tandem of Jim and Dan Miller.
Constantino sat down with MMAWeekly.com to talk about where he came from, his job before he got into MMA, and what really bugs him whenever people talk about AMA Fight Club.
