Personal Defense Industries LLC

Kore Self-Defense is the Personal Defense Industries’ physical training center located in Loudoun County, Virginia providing self-defense training built from a Krav Maga Curriculum originally developed by Eyal Yanilov. Building from this foundation, our curriculum is fueled by continuous research in the evolution of conflict and violence in the post-modern world. Unlike other Krav Maga based programs, our goals are not based on a systemic martial arts paradigm. We focus instead on what is relevant to our students now – today.

Krav Maga & Chiron Training

Krav Maga is our “hardware” and reality based self-defense is our “software”. Our Program Developer & Owner works collaboratively with Chiron Training & the International Violence Dynamics Team to keep our principle based self-defense training program relevant, effective, and current. Once certified, our instructors are required to continue their training; keeping their physical and instructional skills current. Like Karate, Brazilian Jiu Jitsu, and other martial arts, students can train and test for ranks designated by patches as a nod to our military history.

Before you step on the mat,
we encourage you to meet our team.

Mike Devine
Mike DevineProgram Manager, Certified Instructor, Kore Warriors Training Coordinator
Mike has been a practicing Martial Artist for 16 years. He trained in Tae Kwon Do to earn his 2nd Degree Black Belt and Head Instructor rank. While training and teaching in TKD, he provided instruction in both Adult and Kids’ classes. His Tae Kwon Do experience expanded into Hapkido and Judo.

Mike has been training at Kore since 2013, eventually earning his instructor certification. He is the acting program for Kore’s Warrior (youth) program and brings his expertise to the adult program as well. Mike shares that his
training has helped in all aspects of his life, particularly in his work as an armed security officer.

He credits Kore with his ability to apply appropriate logic, timing, and responses in handling difficult situations: “The basics we practice with de-escalation, timeline, and situational awareness are my go-to tools for each interaction with the public. Learning to “other” myself and take the emotional responses out of how I interact with clients and potential problematic people are the foundation of how I operate thanks to Kore’s training and our affiliation with the people from Violence Dynamics. I love being a part of this tribe with all the people and families that help make us who we are.”
