Kru Sam is “one in a million.” I don’t think every fighter can say they’ve been trained, cared for, and carefully guided by their trainer in the way Kru Sam has done for me. What he has given me – a true lesson of the art, the sport, a different perception of the fight game, mental/strength, muay thai’s history, tradition and culture,… I am so grateful for and so fortunate to have been taught.

More than twelve years ago I was introduced to the are of Muay Thai kickboxing by Kru Sam Phimsoutham. Kru Sam’s coaching techniques led me to my first National title. From him I learned may of the techniques that I have used throughout my career including those that I teach to my own students. His patience, skill, and vast knowledge or Muay Thai, combined with the ability to communicate that knowledge to students of varying backgrounds and fitness levels has made him one of the top trainers in the country. It’s no wonder he has produced so many great champions. Wrath James White

The teacher asks his student “Why do we study martial arts?” The student answers, “To be a good fighter.” The teacher replies, “We study not to become a good fighter but to be a good person, for all of life’s lessons can be found in the pursuit.” Thank you Kru Sam for this knowledge.

World Team USA Champion & Head Instructor

I’ve always appreciated Kru Sam, but I never realized the extent of his greatness as a trainer and person until I was gone. NOw that I’ve ventured out on my own I realize that Kru Sam is one of a kind. Although I am miles apart and no longer with him, he still cares for me and all his other fighters that have left. He didn’t have to show us that he still has our backs or do anything for us… BUT HE DID, and expected nothing in return. While I was with him he loved and took care of me like I was family. He put so much work into me. To know that he still cares is why he will always be part of me and will always be in my heart. No matter where i go or what I do – I WILL NEVER FORGET WHERE I CAME FROM!
