Traditional Taekwon-Do International (TTI) is a Christian-oriented association for Oh Do Kwan-style (Chang Hon) Taekwon-Do founded in January 2015 by Michael L. Hadsall. From their website: The TTI is a non political, not-for-profit, Korean Martial Arts organization, that has a strong Christian martial arts history and organizational ethic. Many Schools, Institutes and Dojangs are Christian Martial Arts Affiliates. We are not exclusive in this regard, as we also have Affiliates that are not Christian centered in their teaching. We do not discriminate in this in this area.
