Ryan Duffy

Tae Kwon Do Instructor

Hello my name is Ryan Duffy and although by now I’ve been at MAUSA for more than half my life, I was reluctant to start. I ignored multiple suggestions by my father to start doing martial arts, instead choosing the regular circuit of team sports. But, before long I was making friends and learning interesting new skills; I was hooked. Some belts came and went in a blur, while others dragged on for what felt at the time like many months. There were highs, like competing in 3 national tournaments, and lows, like getting a back kick in the mouth and being brought to the ER. But through it all, I relied on the instructors and my peers for motivation. And now, as an instructor, I have the opportunity to guide children down the same path I myself traveled. For this responsibility, I am immensely grateful. I only hope that one (or more) of my students go on to become a better educator and motivator than I.
