Coach Jeremy Lopez
Contortion Jiu Jitsu Program Chief Instructor
Coach Jeremy Lopez is a high level Jiu Jitsu competitor with over 90 tournaments under his belt. He began training Jiu Jitsu in high school after watching one of the first UFC events and seeing how well Jiu Jitsu competitors fared. The major attraction to him was that flexibility and technique could be used in jiu jitsu to minimize the amount of damage sustained by an opponent while still gaining victory via submission for the Grappler. "A good match is where nobody is seriously injured"
With a well-rounded martial arts training background including wrestling, striking and Judo, Jeremy has won 15 MMA matches in his career total of 17 sanctioned and unsanctioned matches. King of the Cage, Gladiator Challenge, Kage Kombat Monsters, Born To Fight, and Vale Tudo Inc, are some of the venues where Jeremy has competed and come away victorious.
In 2004, Jeremy traveled to Brazil to train with the likes of 5x Pan Ams Champion Vinicius Draculino at his school in Rio De Janeiro. He described the experience as being in a shark tank: there were 20 black belts practioners in any single class as opposed to the one or two black belt practitioners per class here in the USA. Upon his return, he was approached by the well-known MMA industry pioneer, Tapout, to represent their brand and remained on their roster of sponsored fighters for several years. If you're lucky, you'll spot Jeremy driving around in his sleek black Porshe 911, gifted to him by Team Tapout!
Jeremy has trained in numerous Jiu Jitsu Academies such as the 10th Planet in Hollywood with jiu jitsu phenom and founder, Eddie Bravo. Also with multiple time world champion Fabio Leopoldo. Honing his skills in guard defense, takedowns, aggresive top control and emphasizing "position before submission", Jeremy has been teaching Jiu Jitsu privately and found his way to the Budo Ryu in 2009 where he founded Contortion Jiu Jitsu. He is pleased to be a part of such a fine teaching staff and loves helping new and experienced students better their skill set.
