“The entire treatment was explained in detail and everyone in the office was very helpful, friendly and patient. My 9-year-old daughter was very nervous and reluctant about everything, but Crystal was able to quickly build some rapport and the appointment went smoothly after that. Thank you!!” — Emily Thompson “The orthodontist was phenomenal. I had an issue with a permanent retainer I had put on out of state, and the office got me seen the next day, and the doctor was very prompt and thorough. Price was extremely fair. Highly recommend.
