I am John Guarnieri, owner and head instructor at 603 Karate in Northfield, NH. 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 always a student first. I’m humbled to study Uechi Ryu under my instructors, Grandmaster George Mattson and Sensei Justin Testa.
