World Team USA will teach you about your strengths, how to build your confidence, how to relieve your stress and how to find the discipline to reach your goals.  Live your dream!

The Team USA staff goes beyond the call of duty to teach our students the self-respect, confidence, and discipline that we have learned through the practice of martial arts.

We believe that in order to service our students properly, all instructors must be totally committed to the martial arts.

We wholeheartedly believe that there is no such thing as a superior style of martial arts and no such thing as having the best Muay Thai school. If that were the case, everyone would take only one style of martial art and everyone would be attending only one school. Thus, we offer Muay Thai only to those whose personality, goals and lifestyle fits with Muay Thai at Team USA. We respect every style of martial art in the ring and we offer Kung-Fu as one of two options for Kids.

At Team USA, students learn that through dedication and perserverance, all goals in life are within reach. Students are encouraged to set short, intermediate, and long-term goals. Each level is important for achieving success, not just in the martial arts, but also in everyday life.

We respect that every student has different goals, whether it is to become a World Champion in Muay Thai or just to nurture the mind, body and spirit.

We would like to thank you for your interest in our martial arts academy.

Joining us will be one of the most rewarding activities for you or your family.

Through the years, our unique programs have brought about dramatic and positive changes in so many people that we’re always eager for the opportunity to share them with others.


What They Say About Us

“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.”


Christine Toledo

World Team USA Champion / VP Lion Fight Promotions

“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.”

John Ellcessor

World Team USA Champion & Head Instructor

“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

World Team USA Champion

“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!”
