For years after moving to AZ, I would still travel back home just to see my dentist due to some unfortunate experiences w dentists in the valley.  After 9 years, I decided to find someone local, permanently. Dr. Liu is by far one of the best. He is extremely meticulous, caring and very good at what he does. I've had more than a handful of fillings done by him, and every single one has been as pleasurable as an appointment to a dentist can be. Not only is he a great dentist, but a good business man, who understands customer service and honesty.  I would strongly recommend him!
