Brian Delapena

Brian has been training in WTUSA under Kru Sam’s Master Muay Thai.  Muay Thai has driven Brian Delapena to new heights. Without it, Delapena would not have been able to achieve all that he has since his the start of his training. Delapena struggled with confidence during his school days, and was forced to drop out of college. Once he started learning the Muay Thai with World Team USA, he regained self-assurance, work ethic, ambition. He went back to school, and furthered his studies onto becoming a high school math teacher as well as a Muay Thai instructor here at World Team USA. Delapena hopes to continue to challenge himself and win championships.

TJ Arcangel Birthday Celebration

As a gym and as a family, we want to celebrate TJ Arcangel his 29th birthday. However, the hard work never stops. TJ will spend his birthday training at the World Team USA, celebrating it with his second family. “A fight is a fight, and I must prepare for it”, some of the words of the champion that always continue to encourage us all to push ourselves everyday. As students, we are all very grateful and appreciative for the training, and teaching TJ gives us.

Katie Melanie lam Katie Melanie lam

“The mindset of a champion is to up-bring others”. TJ has been at World Team USA since he was a teenager, growing up and being one of the instructors for the pee wee classes. Today, he continues to teach, and encourage the art of Muay Thai to all people. As a family, we all continue to work hard together.

TJ has had many challenges in his Muay Thai career. However, he has never given up on some of the hardest opponents he has faced. “One of my most challenging, and exciting fight, was my last amateur… As many times as I had knocked the guy down, no matter what he continued to get back up.” Keep fighting, keep pushing.


World Team USA thanks TJ Arcangel for sharing his knowledge to all students that come in. TJ is not only a coach, but a great friend to all who he teaches. An amazing day to be in the gym, and celebrate one of our very own coaches, champion, and friends birthday. Thank you TJ Arcangel.
