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.

Hello students! It's been a long time since I've seen all of you! I've been looking forward to teaching you all again, even if it's not under normal circumstances. I hope that throughout this period of time, you have all been continuing to train, to persevere, and most importantly, to grow. I'm excited to be your karate instructor host for tonight, and I hope that you are able to attend this evening's zoom class! I hope to see you all soon!

Let us know if you need to be added or have questions. Our email this week explains our plans for testing in April and how our online process will keep working for us through April. We are hoping to be back to the school with classes on May 1, but we don't know yet what that will look like. Until then please keep working hard and we will see you all online for testing!
