The ETO foundation is Korean Tae Kwon Do. Tae Kwon Do is a Korean style of martial arts that dates back to the Koguryo dynasty as early as 57 BC. Today it is one of the largest organizations of martial arts in the world. Missan Edwards, ETO's founder, is an accomplished Tae Kwon Do competitor and instructor who strongly believes that martial artists should continue to evolve and not limit themselves to only one style. ETO has developed a unique martial arts program that establishes Tae Kwon Do as its primary foundation. It combines Tae Kwon Do practices with Chinese, Japanese, and American techniques coupled with safe exercise principles.
