"I wanted to get braces and wanted to get it from a good orthodontist. So I did my research and went to 4 different consultations including one from Legacy. The other orthodontists said that I wouldn't need any extractions, even though I had crowding. However, Dr. William Chen and Dr. Pham from Legacy, recommended an extraction due to crowding, which made more sense, because if I didn't get an extraction then my teeth would extend out. So I decided to get my braces done here which I love going to. The doctors and staff here are welcoming and friendly every time I walk into the office. They take their time working on my braces and never rush. The cool part about going here is that they have this rewards system called "Legacy Cash" where you get these money cards and if you earn up to a certain amount, you redeem them for prizes such as movie tickets, go kart racing, ipods, and even an ipad! You earn them by going to your appointments on time, getting your regular cleanings done, and other things to motivate you. Overall I love going here and definitely recommend this office to anyone who wants braces done by professionals who know what they're doing and who take their time working on you."

"Dr. Chen and the staff at Legacy Orthodontics have been amazing. I decided to fix some minor problems in my bite as an adult and couldn't decide if I wanted to wear braces again. I initially took my son there for his braces and soon after decided to start a treatment plan myself. I couldn't imagine better. It has been easy to make appointments and the staff throughout the office is welcoming and friendly. It is clear they all enjoy working for Dr. Chen. I look forward to a perfect smile again and am truly glad I decided to have my family be part of the Legacy Orthodontics family."
