Leslie, Dr Mastroianni and the Amazing Smiles team made my daughter's week and we are so grateful! This Saturday is Homecoming and for some reason my daughters teeth start becoming discolored 3-4 months after they are cleaned. Dr. Mastroianni and Leslie went above and beyond and polished her teeth to show off her beautiful smile! You made our day and we are grateful you recognized how important it is to show off a beautiful smile. Her homecoming pictures will now be so much better thanks to your generosity! Thank you.

I had a really bad experience with the orthodontist I went to before this one but once I got here I was upset I didn't go to them in the first place. They even took me in even though I had braces still from my old ortho. Everyone is so friendly and helpful and they are very accommodating to whoever needs it. They finally have my teeth the way I want them. So glad I found this place.

This place is amazing!!! From the initial call, the consultation and EVERY VISIT there after, has been nothing short of wonderful. Everyone is always so friendly, and they really welcome their patrons. My Invisalign process has been seamless, and in my opinion, the cheapest around town, compared to all my other options. If you're considering Amazing Smiles Orthodontics, then DO IT!!

Not taking my after care seriously as a teenager, I ended up as an adult with braces. I went with the metal brackets to ensure my compliance, as Invisalign is not something I could commit to. I really enjoyed my time with Amazing Smiles and I'd highly recommend to anyone who is looking. First, the appointments take like 10 minutes, so you're in and out. BUT also not rushed at all. Second, I feel like cost is fair. Orthodontics are expensive, but they worked with me to create a feasible payment plan. Third, the doctors and the techs are all so nice. They really make you feel comfortable while still being firm and taking my care seriously. Last, the office itself is great, well designed and welcoming. Again, I'd recommend to anyone looking.

What an unexpected blessing we received today! Recently, my daughter's teeth began looking really bad. We had to cancel her last dentist appt due to COVID and the next appointment is still more than a month away. We thought getting a new retainer might help because her current retainer is in bad condition. Today she went in to have her retainer made and came out of the office smiling beautifully and confidently. Thank you Dr. Mastroianni and staff for going above and beyond by polishing my daughters teeth without us asking! She started the day hiding her smile and came out of your office displaying her amazing smile! You made our day and we are grateful you recognized how important it is to show off a beautiful smile. Her homecoming pictures will now be so much better thanks to your generosity! Thank you.
