I started my invisalign treatment in Septemeber 2010. So far I am happy with the progress of my teeth. I chose to come to Dr. Yao because he is very knowledgeable and the only Diamond Certified Orthodontist in Northern California, also his staff was extremely nice and attentavie. I would definatley recommend Dr.Yao to anyone who wants top of the line orthodontic treatment.
