If you are looking for authentic martial arts school visit Dynamic Martial Arts irvine. Ive been training here for years. They teach Korean Taekwondo, Hapkido, and Korean Jujitsu, it is Korean Karate. The thing that makes this school special is that the owner of school is always teaching all the classes. Not like most of schools in Irvine. It is not a Franchise. Im getting my First son into the program as soon as he turns 5 yrs old. They really have great CHILDREN PROGRAM AND ADULT PROGRAMS.
