I really like Dr Whang a lot. He's very kind and works well with all ages (I brought my 6yo son for the first time recently). The office, however, runs very slowly. Every time I come I end up staying for way longer than I expect I should. We were there for two hours. I just really feel like too many patients are scheduled too close together, so that we all end up waiting on top of each other. I'd like to be there for less time.
