Your Instructor
Master Thohsathep Sitiwatjana (Master O)
Thohsathep Sitiwatjana was born into a martial art family. The legendary Grand Master Toddy, a.k.a. Father of Muay Thai who brought Muay Thai to England, is his eldest brother. Under the influence of his brothers, he started practicing Muay Thai at a young age of 5. After graduating from the university, he went to England to teach Muay Thai together with his older brother Master A, grooming a number of Muay Thai champions. After returning to Thailand, he became the Head Master of Master Toddy's Muay Thai Academy in Bangkok, Thailand, having trained hundreds of instructors and fighters over the years, including the recent WBA South Asia Champion Oscar. He has developed his unique style of teaching, which is systematic, methodical, and progressive. It has helped a great number of Muay Thai and Krabi-krabong practitioners break the bottleneck and made leaps and bounds in their art. During this time, his private Muay Thai and Krabi-krabong classes became the most sought after classes in the school. People all over the world travel to Thailand to learn from him.
