Hi P.,
Hands down, Yims Taekwondo on Greenville Ave. He's been at this for 34 years and is amazing with kids. My son is in his third year. He has a policy of the kids keeping a chart which he issues that shows character development and responsibility. The kids fill out the chart each day ( parents can add on responsibilities as well) . After they reach their goals they are awarded medals in a ceremony. It is a crucial part of the process as TKD is as much about emotional and mental discipline as it is about self defense. The kids continue to do these charts throughout the belt levels and cannot attain black belt status without them.
On a physical level, my child is incredibly strong and at age 11 I feel could give anyone a run for their money if they tangled with him!
Yims has a 29.00 special where you get two lessons and a free uniform so you can check it out!
Good luck.
K
