Who is the Camp for? Otis Ridge Martial Arts Camp is open to both boys and girls from 8 - 17 years of age. The only requirement is a desire to learn and share in the Martial Arts. Our instruction is in accordance with all styles and ability levels. Beginners are welcome and often progress at a more rapid pace due to the program design. Intermediate and advanced students benefit from the variety of styles taught at the camp. The ability and opportunity to cross-train has produced many improved students when they return home at the end of the summer.
