Kru mark Klemm has the best Thai boxing in Massachusetts.  He is still my number one sparring partner.  He knows his Thai boxing inside and out.  I'll give a testament to his Thai boxing -- John Howard approved!!!

I've had the pleasure & honor to have trained with Kru Mark Klemm this past year. I've been more than impressed with not only his knowledge but his ability to teach it as well. His students excel and all fight well. I'd be honored to have him as a teacher, he knows his craft.

His depth of knowledge and attention to detail during instruction is unparalleled in the sport .  And best of all, not only will he teach you how to do it, he’ll get in there and hit you with it too! Class act, no-brainer. Take the class thank me later!

After training with several boxing and Muay Thai coaches around Boston I discovered the best, Kru Mark Klemm.   He is dedicated to both sports and possesses the perfect qualities of a trainer and coach. He is knowledgeable, skilled and patient.  He truly cares about all of his students, from the beginner to the professional fighter.  He takes an active interest in everyone's progress and training. Kru Mark is especially gifted at teaching younger children, making fitness fun and encouraging a love of Muay Thai. Many of his former students will be making the drive north to train. Fitness, self defense or competition, -- Kru Mark is truly the best.
