On May 1, 2022 Klaas Barends will teach another seminar in Bangkok at Martial Arts Academy Thailand. This school is run by master Attawiboon Kampansak who teaches hapkido, taekwondo and nunchaku.
It will be the fourth time Klaas is a guest instructor at the academy. It has become a tradition for him to teach there whenever he visits Thailand. If you are interested in joining the seminar, you can contact master Kampansak via Facebook.
