The World Traditional Taekwondo Union (WTTU) was founded by H.U. Lee in the fall of 1990. The WTTU is a branch of the Songahm Taekwondo family that also consists of the American Taekwondo Association (ATA) and the Songahm Taekwondo Federation (STF). The ATA encompasses member schools in the United States and the STF includes member schools in South America. The WTTU covers the remaining portion of the world.
The continuing vision for this organization is to unite martial artists worldwide in an organization that emphasizes "Traditional Values," while utilizing the most advanced concepts and philosophies in the classroom and in business. The WTTU has licensed schools in Canada, England, Portugal, Germany, South Africa, Japan and Sweden.
