Preston “The Predator” Peters
Muay Thai

PRESTON “THE PREDATOR” PETERS is a native San Diegan. At the age of nine, Preston became interested in the sport of Muay Thai when he saw the movie 1989 film "Kickboxer" starring Jean Claude Van Dame. He couldn't find a Muay Thai school at that time so he started his Martial Arts career in Tae Kwan Do. After two years of training, he realized TKD was not the sport he was looking for. In 1999 he started training in boxing and Muay Thai under the instruction of Heath "Cowboy" Harris. In 2004, he traveled to Phuket, Thailand to train Muay Thai under the instruction of Owner/Head Trainer 'Tuk' of Rawai Muay Thai gym. For three months, Preston trained and made his pro Muay Thai debut. His fight experience includes 17 pro fights in San Diego, Los Angeles and Thailand, fighting out of Banlga Stadium, Patong Stadium, and Suwit Muay Thai. His dedication to the sport led him to move to Thailand in 2010 for nearly two years where he continued to fine-tune his skills, teaching and fighting out of Rawai Muay Thai gym. In October 2011, Preston came home to UND1SPUTED to share his knowledge of Muay Thai. He is available for private instruction.

Berlin “Black Bomber” Kerney IV
Boxing

BERLIN “BLACK BOMBER” KERNEY IV started his career as a Dental Technician with USN where he started boxing in 2002 at the age of 18. During his 4th year of service, he was stationed in Japan by way of Yokosuka City. He soon learned being an American Boxer in Japan has its advantages. “Everyone wants to throw a shot at the
gaijin. With everyone wanting to step in the ring, you learn real fast.” Berlin learned firsthand of the pride, dedication and determination Japanese fighters have for the sport. He then separated from the Navy to pursue his boxing career in Japan—but before he did, he visited home one last time. Upon returning to the United States, he walked into UND1SPUTED at El Cajon and hasn’t made that flight back to Japan since. He is currently focused on building a solid amateur record before going pro. He is available for private instruction.
