Linda R. says, "Sensei Russ Costello is an outstanding GoJu instructor. I say this objectively, because I have trained for more than 40 years with other instructors. I remain totally faithful to Sensei Arakawa and Sensei Lee in Hawaii where I earned my 3rd dan many years ago. But I no longer live in Hawaii, and after a training hiatus of several years, I found Russ Costello, who helped me revive my GoJu spirit. He's a walking encyclopedia of the history and meaning of GoJu Karate, and he readily shares his wisdom. In the dojo, he teaches with intense attention to detail and to the "art" form of GoJu. He took a keen interest in my progress, and I feel my kata and technique have improved immensely since I've been training with him. I've also noticed how he does the same with his other students. He cares sincerely about the well-being of his students, whether we are in or outside the dojo. If you have an interest in studying GoJu Karate, I strongly recommend you join our family!" Read more
