Not just your typical everyday martial arts school. No belts rankings but no contracts, affordable monthly (more affordable than most schools in the area) and real effective self defense from JKD to Silat to boxing and Muy Thai. If you are looking to earn belt rankings, this is not the school for you but if you want the effective knowledge from a real martial artist who's been written in newspapers and magazines, hosted numerous martial arts seminars and performed in many events such as The Pacific Rim and Indonesian Day, then give it a try. HIs students are easy going, friendly, and very supportive to new students. Instructor Rocky Twitchell is as real as it gets.

She has made huge strides lately thanks to Robert and his staff. She has gone from not wanting to go to Kung-Fu to actually looking forward to it. Robert teaches them challenging lessons and also a lot of fun moves and exercises. Each week, the 5-8 year old class learns a new lesson on Monday (or a refresher on a previous lesson) and does fun exercises on Thursday. Students often pair up and work on lessons together with the help of an instructor. Classes in this age range run 40 minutes--just the right amount of time. It can be hard getting beginners interested and motivated initially (and it could take several weeks to get there), but it's worth it if you stick with it. Highly recommended!!

I am a young 65 year old with severe scoliosis and stenosis. I look forward to class each week. Eileen has such a calming , positive energy and has so much knowledge about the body and the healing benefits of Qi Gong. At first I did many of the exercises from a chair, but I am now able to complete the class usually without this modification. I also see a big difference in my breathing when I'm taking walks. I am able to walk up inclines without getting winded. I was afraid I wouldn't be able to follow the form in the online class, but Eileen explains things very clearly, and positions her body so it is easy to follow. She also takes questions at the end which often help me. I am very lucky to be able to be her student because I live in Oregon. Though I can't wait to be "on the other side" of this virus, I hope her Zoom classes will continue when life gets back to normal.
