All of my three boys trained at Doerksen Taekwon-Do. They started at when they were six years old until they graduated in high school. Two have attained first dan blackbelts and one second dan blackbelt. I believe that somehow they learned a lot from their trainings and have helped them become into what they are now, all professionals, law-abiding citizens . Thanks a lot Mr. Doerksen. Elmer T.
