Our whole family has trained with Master Choe from white belt all the way to black belt. Both parents started when we were over the age of 40, and we can personally attest that Master Choe does a great job with different age groups. He has excellent credentials, training is very high quality because he does it himself instead of farming it out, and he is committed to keeping his prices affordable. They are upfront about prices--unlike many other schools that try to get you in with special price offers and after you're hooked start charging much higher prices, they charge a consistent monthly rate regardless of your belt level and allow you to take unlimited classes.
