Head Instructor: Gershon Ben Keren (5th Dan)

Welcome to Krav Maga Yashir! We are located just North of Waltham, MA, off of I-95 (Exit 53). Head Instructor Gershon Ben Keren has been practicing and teaching Krav Maga since 1993 – he is a 5th Degree Black Belt and a 2010 inductee into the Museum of Israel martial Arts is Herzliya, Israel. He has authored three books on Krav Maga (Tuttle Publishing) and has conducted two Google Talks on Krav Maga.

Krav Maga – meaning Contact Combat in Hebrew - is the name/term used by the IDF to refer to a number of fighting systems/styles that it teaches to its members; all share a common methodology and approach, but not all are the same e.g., what is taught to the infantry is somewhat different to that which is taught to more covert units/agencies, such as the Yamom, or Shin-Bet etc. This is because different agencies have different remits e.g., an infantry member is going to have less of a need to use control and restraint techniques than somebody engaged in border control etc. This is one of the reasons why it is important to know, who a Krav Maga instructor has trained with, and where their Krav Maga “style” comes/originates from. You can learn more about Krav Maga by clicking here, or about its history and development by clicking here. Head Instructor, Gershon Ben Keren, has trained with various instructors including Dennis Hanover & Yaron Hanover, Eyal Yanilov, Miki Assulin and Avi Moyal etc., some of whom he has brought to the Massachusetts to conduct seminars. He has also taken students from Krav Maga Yashir to train in Israel.

Our school teaches only Krav Maga – we don’t mix in combat sports, such as Muay Thai and BJJ etc. – and has a full and comprehensive syllabus, which deals with unarmed and armed, attacks and threats, that are committed by both single and multiple assailants etc. We train in different environments (indoor and outdoor), and for all the different dimensions of a fight e.g., standing, on the ground etc. If you are interested in experiencing authentic Israeli Krav Maga for yourself, you are welcome to attend one of our introductory seminars.
