Big John McCarthy was born on October 12, 1962. He is considered the pre-eminent referee throughout the world for mixed martial arts (MMA), beginning with his involvement at UFC 2 over 23 years ago, and is a much sought-after figure when it comes to historical knowledge of the sport of MMA.

It is unlikely that anyone has been more prepared or destined to become an MMA referee than John McCarthy. McCarthy has been a police officer with the Los Angeles Police Department since 1985. As a student of the legendary Rorion Gracie, he has also experienced the rigorous training associated with Brazilian jiu-jitsu. Having excelled at both, it was inevitable that he became an instructor.

John McCarthy was awarded his Tactic/Self Defense Instructor Certification by the LAPD on August 12, 1993, and taught for the department.
