Catonsville Seido Karate provides training for self-development, self-defense and physical fitness for adults, teens and children. Our instructor, Sensei Tom Swiss, is a fourth-degree black belt with over twenty-five years of experience in karate. Classes are held at the Catonsville Y -- just 20 minutes from downtown Baltimore, near UMBC and CCBC Catonsville. Our class size is small, so each student receives individual attention.
