They are so welcoming when you walk in the door, so helpful. Made sure me and my son was comfortable. They answered all my questions, and made sure I knew everything I needed to know about the appointment. I truly appreciate you all.

Incredible first visit!! Megan & Dr. Arun are friendly, informative and professional while being down to earth and practical. They explained exactly what to expect and explained our options. My teenager was nervous about this consultation and getting braces but now he feels relieved and in great hands. With everything going on in the world it’s a pleasure to still find caring compassionate and friendly people. We will definitely be referring friends and family to Plaza orthodontics. .

I love this place. First and probably more importantly my son’s teeth look great. But everyone there is so warm and friendly. It’s a pleasure to be there. They are attentive and keep you informed. There were no surprises. I easily give Plaza Orthodontics five stars. I really appreciate when there is not only great results but it’s also actually a pleasure to be around everyone there.

This office is the MOST unprofessional you will find. I would not go here again for Invisalign if I had to. They do not keep their financial books correctly then they tell you that you owe more money. When you prove you paid them with bank statements they tell you that they don't believe you. I spent 1.5 yrs giving them the same bank statement and again today I was called a liar they didn't believe that I paid them. They promised that everything was included yet then try to charge you. I also over paid them and they refused to apply that towards a permanent retainer. You are denied access
