Good but not great
It is a good school Mr Black is very nice but the kids classes are too short only 30-45 mins needs to be an hour, and he has them too early, classes start at 4pm, and my kids don't get home from school till 3:45 even though we live a few blocks from the school we still can't make it in time with traffic.
He should start all the classes at 4:30 so everyone has a chance to make it to class everyday. The kids classes need more instructors, and less kids per class and they need to focus more on TKD and less on "fun time".
When it is close to testing or tournament time they really do a lot to get everyone ready and the classes are great but after testing they slack off for 2-3 weeks at a time.
Overall it is a very positive school and he can be a great teacher honestly the best I have ever seen especially with my 7 yr old but it is not consistent and 30 mins per class is not long enough for the price. While I do recommend it their is room for improvement.
