Sedthee Fight Club was founded in 2024 in Chiang Mai, Thailand — built not by businesspeople, but by two fighters who have spent their whole lives in the ring. Our mission is simple: pass on authentic Muay Thai, exactly the way it is taught and fought in Thailand, to everyone from first-time travellers to professional fighters.
Built by champions
Our head coach, Sedthee Erawan, is a Channel 7 Stadium Champion (118 lbs) with more than 150 professional fights. After becoming Southern Thailand champion at a young age, he moved to the big stage in Bangkok, became a Channel 7 favourite and won the Channel 7 Tiger Cement 16-man tournament. He has been coaching since 2015 and leads our daily sessions and fight preparation.
Teresa Wintermyr is a 2× WMC World Champion (118 lbs) with 95 professional fights. She has been in Thailand since 2008, fighting Muay Thai full-time for over a decade — including a 2nd runner-up finish in the World Muay Thai Angels tournament. A specialist clinch fighter, she leads our women’s training and corners our fighters on fight night.
A team of real fighters
Behind Sedthee and Teresa stands a full team of Thai professional fighters — boxers, kickers, clinch specialists and technical muay femeu stylists — many of whom have trained since childhood and fought dozens of times. Whoever holds the pads for you has truly lived this sport. Meet the coaches.
