I am John Guarnieri, the owner and head instructor at 603 Karate.  Martial Arts has been a passion of mine for many years, and now I have the pleasure of sharing that passion daily. 

 

I have studied many martial arts over the years, but I fell in love with Uechi Ryu Karate due to its practical effectiveness while maintaining its traditional roots.  Studying Uechi Ryu Karate helped me develop tremendous self-confidence in everything I do, including working patrol in the 9 years I served in NH Law Enforcement. 

 

Although I am now a school owner, I am a student first and still study Uechi Ryu under my instructors, Sensei George Mattson and Sensei Justin Testa, as there is always more to learn and pass on to others.

​

Contact me if you would like to experience what consistent Karate training can do for you.  It would be my pleasure to help you get started!
