After speaking with Dr. Liu, I have decided to raise this review to a 3 star. I believe Dr Liu is good intentioned and treats his patients just like he was trained to do so. He has my respect as a person, but I still disagree with a few of his practices- particularly his hesitance to avoid newer technologies, like Invisalign. His recommendations for you will likely include "shoot from the hip" techniques like straight-wire braces, etc. If you are looking for braces, look no further than Dr. Liu. However, I encourage all readers of this review to evaluate other options and even speak with other orthodontists. There are many other cheaper technologies out there and with the rise of companies like smiledirectclub (i'm not recommending this company, just using it as an example), braces might not be the best option for you, or your child. Remember, your child doesn't NEED braces just because one Doctor in a white coat recommends them. Think it through for yourself don't rush anything.
