My grandson, Jonathan began training at the Easton Brazilian Jiu-Jitsu facility in Castle Rock, Colorado during May, 2013. As Jonathan approaches his first year, allow me to share our BJJ experience and appreciation for his professors, coaches and staff who support all the students at Easton BJJ.
As a typical 5 year old boy, Jonathan's attention span was minimal and his respect for his teachers and parents were typical for a 5 year old boy too. After a few months, Jonathan turned 6 years old and we could already see that a fundamental change in his attitude and behavior was underway. After the first six months of training BJJ nearly everyday, Jonathan competed in his first tournament and earned a 3rd place finish and was beginning to develop a very calm and confident attitude. His behavior and grades at school were beginning to fundamentally improve given they had been a source of concern earlier in the year. BJJ is an awesome education and example for any young girl or boy to help realize their full potential!

BJJ is hard to explain, you either love it or can't understand it. The Easton instructors eat, live, and sleep BJJ. They've all given up more lucrative careers to pursue BJJ and teach it to others. They compete and medal at national competitions (bad ass). The work is hard, but the atmosphere is very friendly, welcoming, and encouraging, I've trained there for over two years now, lost 40 lbs., made numerous new friends, and have the confidence to compete at large national tournaments. I'm am challenged emotionally, physically, and most of all mentally. It's made a real difference in my life and I plan on doing it for many years to come and I'm over 60.
