John Danaher Biography
Born in New Zealand John Danaher started grappling late in life (28) in New York City. He was working his way through grad school (later finishing a Masters Degree in Philosophy at Columbia University) working part-time as a club bouncer, while lifting weights to stay fit while weighing around 250lbs (113kg) at the time of his first jiu-jitsu experience.
Having seen how some of his bouncer colleagues handled fights on the job by using their grappling experience, John saw the potential those techniques carried for his own safety and decided to take a class. One of his friends already trained jiu-jitsu at the time and took Danaher to his first lesson.
After the trial class, jiu-jitsu’s potential as a self-defense mechanism was even clearer to Danaher who believed it to be a good tool to fend off drunken degenerates at his doorman job. He had little or no real idea of how grappling worked at the time, in fact, he mentioned when interviewed by the “Renzo Gracie Cape Town” website that he didn’t have a very flattering perspective of wrestling:
“I’d seen wrestling in the Olympic Games, and I had a very low opinion of it, It was kind of like a homoerotic sport where guys just grab each other, whereas in a real fight, a guy would just punch the other guy and knock him out and it would be over, right? Bruce Lee would just sock him in the head.”
Acknowledging jiu-jitsu’s value helped John push through his training sessions, never truly enjoying it. It wasn’t until RGA was depleted from two of it’s most prominent instructors, Matt Serra and Ricardo Almeida that Danaher truly embraced the sport. Danaher was invited to coach and help replace the two aforementioned standouts, he was a purple belt at the time and took it upon himself to be the best instructor he could possibly be. Although he had no competitive experience, his highly inquisitive mind did not rest until he mastered the coaching aspect of BJJ.
His obsession with grappling placed him on the mat 12-14 hours per day, Renzo Gracie said about Danaher’s behavior: “he [Danaher] does jiu-jitsu every day; we can’t get him out of here. I think he would come in on Christmas if we would let him.” His hard work paid off as Danaher received his black belt on April 2nd, 2002 together with his friend and training partner Shawn Williams.
John Danaher is also known for his eccentric side, a self-diagnosed obsessive-compulsive JD seems to rarely leave his jiu-jitsu rash guard in the closet. In one episode of Matt Serra’s video blog for UFC 109, Serra told the story of how John Danaher had come to his wedding wearing a rash guard.
In working at the Renzo Gracie Academy in New York, Danaher also helped the development of MMA fighters such as George St. Pierre, which shed some light into his persona to the broader spectrum of fans involved in cage combat, however, it would be his creative approach to the leg-locking game that gained him the recognition of the grappling community. His innovative system helped Danaher generate a group of outstanding athletes such as Eddie Cummings, Gordon Ryan, Garry Tonon and, to an extent, Craig Jones, all competitors who had fantastic global success in jiu-jitsu. This workgroup of outstanding grapplers would be labeled by jiu-jitsu fans as the “Danaher Death Squad”.
