Sean "Muay Thai Guy" Fagan

The man, the myth... the Muay Thai Guy! 

A retired pro Muay Thai fighter and coach, as well as the owner and operator of Muay Thai Guy, Sean has been immersed in the Muay Thai scene for more than a decade. 

Originally from a small town called New Paltz in upstate NY, Sean began his training under JJ Russo, owner of Stockade Muay Thai in Kingston, NY. Since discovering Muay Thai at the tail-end of a boxing career, Sean has since competed in over 30 fights. He's won two amateur championships (one with a broken arm), fought on national Thai TV, competed on Lion Fight, and won a title at Madison Square Garden.

When not coaching others or training himself, Sean spends time at his New Paltz home with his wife Liz, their son Theo, and their dogs Suay and Tilly.
