Gershon Ben Keren has a Master’s Degree in Psychology, and is currently studying for a second Masters in Criminology. His approach t o understanding and dealing with violence is research based, and is founded on the latest academic research into violence. This means that the solutions he provides and prescribes are not limited to his own experience, or based on well-intentioned but ill-founded notions and ideas.

He has worked in the security industry since 1990, when he started working in bar and club security, as a doorman. Since then he has worked in a variety of security roles, including close-protection, surveillance, security analytics etc. and brings his experiences – and those of others who he has worked with – to inform the solutions to aggressive and violent situations, that he teaches.

He currently lives and works in Boston, running the Krav Maga Yashir training center there - a 16 000 sq ft dedicated Krav Maga training facility – teaching military, law-enforcement, security professionals, Krav Maga, self-defense and self-protection.
