I heard of Dr. Huang through a family friend -- given his proximity to my home and the fact that my old dentist had become busy to the point where appointments had to be scheduled 3 weeks ahead of time, I made the switch. While I've only been to Dr. Huang for general check-ups, cleanings and fillings, I usually leave with a good impression of his work and services.
His facilities are clean and new-looking; his office has a rather sterile appearance and scent, with pretty recent technology compared to my previous dentist (x-ray machine, chairs, dental lamps). His assistants are usually right on point, and he does pop in from time to time while the assistants are cleaning to make sure everything is okay.
His receptionist also calls 24 hours ahead to remind you of your appointment, and the Saturday morning hours are much appreciated. I've never had to wait long as long as I had an appointment.
The only real complaint I have is the quality of his fillings. He is relatively gentle when performing oral surgery, but I always have a very grainy bite on the teeth that he's filled for me that I've asked him to subsequently reshape (he obliges). I may just have a small mouth, but as he's pretty young this will likely improve.
