Sensei Robert

Sensei Robert is the Lead Instructor at CMAA. He started training at 24 years old and currently holds the rank of Sandan (3rd Degree Black Belt) in both Shuri Ryu Karate and Shintoyoshin Kai Jui Jitsu. His favorite things about teaching are seeing that moment when something “clicks” in a student’s understanding; and learning new ways to deliver information to the students. When he is not at the dojo he likes to spend time on yardwork and working on classic cars.

Mr. Jaden

Mr. Jaden is a senior instructor at CMAA. He started Martial Arts training at CMAA when he was 7. He currently holds the rank of Nidan (2nd Degree Black belt) in Shuri Ryu Karate. He loves that through teaching he can help positively influence the lives of our students. When not on the mat he can be found playing sports and hanging out with friends. His Brown Belt originally belonged to Renshi Matt.

Assistant Instructors

We have several different assistant instructors here at CMAA. Our assistant instructors have all been training in our school their entire martial arts career and are at least Shodans (1st Degree Black Belts). All our instructors are passionate about Shuri Ryu Karate and helping other students achieve their goals along the way. By having multiple instructors, we can provide more personalized attention for our student base. This also allows our students to learn in different ways, making sure everyone is exposed to multiple teaching styles so that each student receives the most out of their training with us.
