Instructor
Upon completing his bachelor's degree in Physical Education at Angthong University, Phon Martdee moved to Australia to open a martial arts centre known as "Muay Thai Boxing Promotions" or best known as "Phon's Gym" under the guidance of the Professional Boxing Association of Thailand in 1989. At this time there were little known authentic Muay Thai gyms in Australia. Martdee began training groups of youths and adults interested in the newly founded ring sport. Martdee then began staging local events placing his fighters up against local BJC, boxing and kickboxing opponents. Over time Muay Thai gyms began opening around Perth allowing for an expanded selection of competition. In Martdee's 22 years of instructing he has trained over 30 champions at his gym which still operates in Northbridge to this day.
