About Mr. James Halonen

I started in karate when I was four years old, and I grew up in a karate family. I also snowboard, water ski and water board, and fish, so as I was growing up I had a lot of sports to keep me busy. I didn’t realize until I was older how valuable karate was as part of my upbringing. Because I was a karate student I learned discipline and focus as well as building strength and coordination. The mental and emotional benefits of karate added to the physical benefits and helped me to become a successful and competent adult.
