I am a father, a master teacher in the martial arts, an entrepreneur, a writer, a mentor, an inventor, a hobby musician, and an adventure enthusiast. I believe in living a healthy, well-balanced life. I am a 6th Degree Black Belt in the art of Kenpo karate. I have over 30 years of experience in Martial Arts, safety awareness, self-preservation and escape tactics. I have run, managed, and owned multiple businesses for almost 30 years, and I have trained tens of thousands of people to overcome obstacles in their lives by developing a stronger mind, body, and spirit.

I created Hammer Defense with the goal to provide awareness and access to practical self defense tools in order for users to protect themselves and their loved ones from potential harm.
