Personal protection is a God given and Constitutional right and Responsibility. It is our job and desire to help all legal and law abiding residents who have a desire to do so, develop the skills, and provide them with the tools needed to do that.


Our mission is to provide the very best training possible. Our Staff of Professional Firearms Instructors and asset security specialists combine their collective knowledge and experience to provide you with the highest quality and most effective training and analysis available anywhere. We can mentor you regardless of your training wants or requirements at reasonable prices. Whether you are new to shooting/personal protection or you are experienced and looking to take your knowledge base and skills to the next level, we can help. Our cadre includes some of the most qualified, knowledgeable and experienced trainers in the area, who have used their skills throughout their military and law enforcement careers locally, nationally and internationally. The foundation of everything we teach is Mindset”, with performance being the focus and proficiency the goal. Understanding the effects of stress on the central nervous system is  paramount. Reformatting it to function appropriately can be the difference between winning and losing. A firearm is simply a tool, the “Mind” is what we use to fight and is the real weapon.
Train Hard, Train Often, Train with the Best, Train with J2 Defense
