Krav Maga is a self-defense system developed for the Israel Defense Forces (IDF) and preferred by U.S. Military and Law Enforcement agencies.  Krav Maga consists of a wide combination of techniques sourced from Aikido, Judo, Muay Thai, Boxing, and Jiu-Jitsu, along with realistic fight training including weapons (stick, knife, and gun) and multiple attackers. Krav Maga is simplistic and instinct-derived, known for its focus on real-world situations and its extreme efficiency and brutal counter-attacks. It was derived from street-fighting skills developed by Hungarian-Israeli martial artist Imi Lichtenfeld.

Joseph Pete, Lead Instructor


Joe found Krav Maga in 2014 while searching for a fun way to add cardio to his weight-training routine.  He was so impressed by the system after the intro class that he signed up right away and began training several days a week.  Joe spent some time with Brazilian Jiu-Jitsu and Muay Thai so he was not a stranger to striking and ground-work, but those systems aren't specifically for self-defense.


Joe became a Krav Maga instructor as a personal development goal, but quickly realized how much he enjoyed teaching people the tools to protect themselves and their loved ones.  He is a certified Level 1 instructor for Krav Maga Worldwide and earned his Level 2 certification with Krav Maga Alliance in 2019. 


When he's not teaching or training for his Black Belt and Level 3 teaching certification, Joe is a proud father and a Director in the Process and Technology practice at an energy consulting firm.

Chinh is currently a Level 5 (Brown Belt) practioner, and Krav Maga Alliance Certified Level 2 Instructor. At the age of 8 he began practicing traditional martial arts in Vietnamese Kung Fu.  His martial arts experience includes Vovinam, Muay Thai, Kali,  and of course Krav Maga.   A friend introduced Chinh to Krav Maga in 2008 as a modern self defense system that was more applicable for modern combat needs.  The concept of being able to overcome threats from weapons and multiple attackers had him sold because this is where traditional martial arts lacked. 

As his passion for Krav Maga grew, he took it upon himself to visit different Krav Maga studios in different cities that he visited.  He felt that it was interesting to learn how each school had its own unique way of teaching certain techniques but a few things remained key!  Identify the threat, counter attack, control, finish, aggression, and physical fitness. 

“Krav Maga isn’t just kicking people in the groin, gouging someone’s eyes out, and fighting.  Krav Maga is a great tool for personal and career development.  You can take from it what you want.” – Chinh Doan
