The program states that it respects every style of martial art, offers Kung-Fu as one of two options for kids, and offers Muay Thai only to those whose personality, goals, and lifestyle fit with Muay Thai at Team USA. The program notes that its unique programs have brought about dramatic and positive changes in many people and that it respects that every student has different goals, from becoming a World Champion in Muay Thai to nurturing mind, body, and spirit.
World Team USA reports a history of over two decades of offering elite Muay Thai training in the San Francisco Bay Area and displays 14 awards. Community involvement includes Kru Sam introducing Muay Thai locally by fighting black belts in the Bay Area, with interest picked up by figures such as Sifu Harlan Lee, Sifu Shane Lacey, and the Lozada family. SFPD Officer Paul Lozada gave Kru Sam his first teaching job at a small academy in downtown San Francisco, and these champions experienced Muay Thai competitions in productions by BJohn Promotions, Scott Coker’s Strikeforce, and Dennis Warner’s World Championship Muay Thai. Kru Sam, along with Coach Cung Le and Professor Navarros, brought the first “smoker” to the Bay Area in 1995.
