My 10 and 18 year old are both studying at Family First Martial arts in Cool Springs. I don't know how far you might or might not want to drive. They believe in a well-rounded student and start it with respect and positive reinforcements. It's not a contract type school. It's month to month. We learned about it from our neighbors and can't say enough good things about it.
From their site
" A modern mixed martial arts curriculum incorporating many styles, such as Goju-Shorei, Muay Thai Boxing, Judo, Tae Kwon Do and Goju-Shorei Ju Jitsu. With a focus on leadership, bully prevention, diabetes awareness, acts of kindness, community projects, the list goes on"

The number listed on the site is their mobile. Give them a call, it would probably be a better representation of the people than what I could give you here.
