HRCA works exclusively with Highlands Ranch Taekwondo to offer martial arts programs for the community. This program is led by 5th Degree Black Belt Master Myong Su (Mathew Cottingham). He has won numerous championships in sparring and forms and has MMA (mixed martial arts) training in Jujitsu, Judo, and Muay Thai. This gives his students a broader range of training as he includes these techniques into his Taekwondo teachings.
