Being a long time martial artist, when i stepped into this martial arts / MMA, kickboxing & JKD school - I was pleasantly surprised to see a fun, safe and fun environment for training martial arts.
One of the things I look for is how the instructors interact with the students... what i found here was that the instructors were detailed yet motivating.
I also watched the kids class and saw the same passion from the instructors.
If your in Greenfield and looking for a martial arts school that will be both sound in instruction & environment - try this school! they also offered 2 weeks free when I was there.
