My teenage son usually hates any kind of medical appointment, but he surprisingly doesn’t complain about coming here. The assistants joke around with him enough to make him relax while still staying professional. His braces needed an emergency repair once after basketball practice, and they fit him in before school the next day. The office can get noisy during busy afternoons, though the actual treatment experience has always been smooth and organized.

So far so good. I have had nothing but good happy care. I started my journey the end of October and loving it and the staff. I go in with a good attitude and i get the same. I did see where some people will leave a bad review do to being late. I get it because i work with a plastic surgeon and if one person is 10 or 15 min late it throws the entire day off. We have to be mindful that when we are late it makes the next person late when they got to their apt on time. Just as we like to be given Grace give the workers some Grace. I have not had the front desk be nasty to me and if they are then that is not good. Front desk sets the tone for the office.

Go elsewhere. Front desk doesn’t answer the phone but will text you back asap. If you need your appointment Rescheduled be prepared to be rescheduled out for atleast 2 months. Overall the service here lacks compared to the price of what you are paying.

I love the Clayton location. Everyone we have encountered is very professional and very knowledgeable. Both of the front desk receptionist is excellent. They are pleasant every time they answer the phone and go above and beyond with every interaction. I would highly recommend this location!
