Nathan’s extremely skilled expertise in the traditional Thai boxing (Muay Thai Chaiya) has certified him to become a trusted Teacher, endorsed by one of the leading Masters of this Art in Thailand – where he had help taught the students of Ajarn Lek’s Muay Thai Camp for nearly a decade.

Having seen his seminars provided for Private Security Personnel, selected Thai Military brigades, as well as people visiting Thailand for learning premium Muay Thai, I can only say that he understands the culture of ancient warfare and the appropriate ethics involved and will be able to teach this ancient Art whilst still keeping the integrity and honours intact.

Not to mention that his fluency in Thai has been a great benefit in teaching to locals who to their surprise still remain in awe after their sessions.

If you like martial arts and your job gives an opportunity to travel a couple of times per year, I would highly recommend you visiting Baanchangthai in BKK and take lessons with Nathan.

I’m thrilled to provide a reference to Nathan Brown, whom has provided me with the utmost commitment to my studies of Muay Chaiya. Nathan richly deserves the title Kru in Muay Chaiya and is an excellent teacher full of good character and meets the highest standards or professional ethics.
