About this pro

My life long passion for sports and the martial arts started when I was a teenager, using my advanced skills in Wing Chun, Muay thai, Shotokan karate and boxing to excel as an All-American high school athlete, and to play football for the University of Southern California. Over the years, I've curated the most effective techniques learned from a variety of combat sports to create my own unique self-protection system that I call "Kuaishou," which translates literally to "fast-hands" in Cantonese. I'm a 5th degree black belt, frequent lecturer, and co-author of the recently published book "Idiots to Monsters: the Essential Guide to Surviving Common Threats and Violent Encounters."  

Our FitSport training facility is fully equipped and I offer both private and group training in Martial Arts, boxing, Muay Thai and Self-Defense. It's fun and a great way to get in shape. All levels welcome.

    Dave Kerr is a well-respected and high credentialed Sifu with the unique teachings for practical self-defense, whether at measured level of response to dealing with just idiots or life threatening monsters. Most importantly, if you are a student of Dave and his team of instructors you are family, and you welcome him to be a part of yours.

    - welcoming staff - instructors: highly skilled and experienced, break down each self defense move then teach us how to build them over time; provide a fun and engaging class where we can make mistakes and learn from them - i always look forward to coming to the facility, even if i'm tired or had to travel far with traffic

  • Randy Quinton

    The training staff are highly skilled and create an environment that welcomes and nurtures students of all abilities, background and ages. The indoor facility is airy, open and spacious and well maintained. There is an outdoor area too. The overall vibe is welcoming, energetic and fun, with the opportunity to not only get fit, but pick up some street-smart self defense skills from the combat sports classes as well. I’m in my sixties and appreciate that. The student mix is eclectic which adds to the enjoyment. I am very happy to have found Defense Kinetics and have been a regular for several years. Highly recommended.

What is your typical process for working with a new student?

I work with beginners through expert level martial artists. Some students prefer to start with a few private lessons before tranistioning to group training, but it's not required. 

What education and/or training do you have that relates to your work?

I have studied various forms of martial arts since I was 16 years old and have been teaching for 25 years. I recently wrote and published a book on self-protection titled "Idiots to Monsters: the Essential Guide to Surviving Common Threats and Violent Encounters," available at Amazon and at local bookstores. 

Do you have a standard pricing system for your lessons? If so, please share the details here.

Private lessons start at $80 (pack of 4 lessons for $320).

How did you get started teaching?

My passion for martial arts was sparked by real-life threats against my family. You can read more about it in my book or I'll tell you more about it in our lesson.

What types of students have you worked with?

I work with kids as young as 12 and adults in their 70's. My techniques are proven and can be learned by anyone with reasonable physical abilities.

What advice would you give a student looking to hire a teacher in your area of expertise?

Many forms of martial arts are not practical for self-defense purposes. I don't teach people how to compete in competitions, or ask them to pay more to earn the next colored belt. Instead, I teach them how to avoid a conflict in the first place through awareness and deescalation. If a threat is unavoidable, I teach my students how to end the encounter quickly (using pain as the great equalizer), and either incapacitating an assailant or allowing enough time to escape.

What questions should students think through before talking to teachers about their needs?

Ask your martial arts instructor if he or she teaches practical self-protection techniques. Spin kicks to the head, swords, or rolling on the ground to subdue an assailant  may be fun to practice but are worthless if you are involved in a real-life threatening situation.
