Ben WeinsteinBen’s grappling adventure began in High School as a member of the wrestling team. His interest in wrestling lead him to try Judo which he continued to practice in the off season. After High School he moved to southern California to attend college and in 2002 started training Brazilian Jiu-Jitsu on campus at Long Beach State University. While living in Southern California, he had the privilege to train with many world class grapplers, compete in numerous tournaments, and earn his purple belt. In 2008 he moved back to his hometown in Northern California and quickly found his place training at Ralph Gracie Jiu-Jitsu Berkeley under Eduardo Fraga. It was there that his Jiu-Jitsu training truly excelled and 2012 was awarded a black belt from Professor Fraga. In late 2010 Ben came to Bangkok to compete in the Thailand Open tournament and travel in the area for a few months. He quickly realized that Bangkok was the place for him and canceled his plans to return home. He is now the head Brazilian Jiu-Jitsu instructor at BKKBJJ.

He has trained in various styles of martial arts and particularly enjoys the combative and self defense aspects of Brazilian Jiu-jitsu. He can teach in both Thai and English.

Krzysztof Hajtalowicz (a.k.a. Chris Haja)Chris began grappling in 2006 in Opole, Poland at a small Brazilian Jiu-Jitsu Club. Even though there was no head instructor the club encompassed true passion for grappling.
It wasn’t until two years later, after having moved to Dublin, Ireland, that Haja would receive official instruction under John Kavanagh (SGB Ireland). At the same time, Chris dedicated himself to improving his stand-up at Bridgestone Muay Thai.
Having made the move to Chiang Mai, Thailand in 2009, Chris began training under Gracie Humaita black-belt, Pedro Schmall at MMA Chiang Mai. Dedicating himself to training both gi and no-gi, Chris was able to integrate his previous training under close tutelage of an accomplished black-belt. He continued to live in Chiang Mai for the next two years studying and teaching gi and no-gi BJJ.
