Hello, my name is John Guarnieri. I opened 603 Karate in 2017 with the goal of helping people build leadership skills and realize their full potential. Since then I have seen tremendous growth in individuals at the dojo both physically and mentally, all while learning a highly effective self defense system.
If you are looking for a fun physical activity, come try a class and meet some of the nicest people in the Lakes Region. 603 Karate offers a safe and encouraging environment for anyone looking to improve themselves.
Thank you very much! -john g
