A great experience with a fantastic instructor, Charlie is a highly talented martial artist who can teach at any level you are at. I’ve been in martial arts for 34 year and was amazed how much he knows and his willingness to share his knowledge. His ability to explain, demonstrate and correct everyone’s individual needs is truly a strength that will bring me back to his dojo as often as I can make the trip from Milwaukee. His students are also very accepting & great to get along with. Mike S

After 42 years in the martial arts, which has included living in Okinawa in 91/92, I was spellbound. Charlie Peterson sensei's understanding and method of studying the art has opened my eyes in a way I could not have imagined. He can both convey his highly advanced knowledge and demonstrate the techniques at speed. A true inspiration.

Top notch world class martial arts instruction and practice. This is a real life protection arts system that is taught in a real world setting. Highly recommended.

T. Kent Nelson / KSK Martial Arts
I have been studying various martial arts for over 35 years, teaching and training, both in and out of the United States. And I can honestly say in all that time that I have never met another person who has the same unique perspective and approach to teaching as Kyoshi Charles Peterson. At the Okinawa Academy of Martial Arts you’ll learn far beyond the basic concepts of self defense, as they surpass the simple choreography taught in most Okinawan/Japanese karate systems, and focus on the quality of movement itself. As one who has previously trained in his group classes for 3 years, and now studies privately with him. I am confident in saying he has a special piece of the pie that I haven’t seen, from any other instructor. Kyoshi Charles Peterson & The Okinawan Academy of Martial Arts is a rare gem in a sea of rocks.
