I took my son to several orthodontists for consults. Many wanted to start treatment when he was very young and wanted to charge me extremely large amounts of money. Dr. Nguyen was very honest and didn't start treatment on my son until 2 years after our first consult. His prices are very reasonable. For the first phase of my son's treatment Dr. Nguyen sent me a refund because my son did as he was told and finished treatment approx 8 months earlier then expected.
