My name is John Guarnieri and I am 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 on a daily basis.
I have studied many different martial arts over the years but I fell in love with Uechi Ryu Karate due to it's practical effectiveness while maintaining its traditional roots. Studying Uechi Ryu Karate helped me develop a tremendous amount of self confidence in everything that I do including working patrol in the 9 years that I served in NH Law Enforcement.
Although I am now a school owner, I am always a student first and still study Uechi Ryu under my Sensei, Christian Maine 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!
