Patient Reviews
“Super nice and clean facility and the staff is extremely friendly. I would highly recommend this location.”
“I had an awesome experience with my consultant, Christina. She and everyone else were so nice and knew what they were talking about. I can’t wait to get my Invisalign treatment started.”
“Expert and professional staff, we arrived early and were seen early. Both procedure for braces and payment were explained in detail and all questions were answered. Will recommend to friends.”
“I just moved to the area and was looking for a place to take over my orthodontic treatment, from the first phone call to schedule an appointment everyone has been extremely nice, welcoming and has provided me with answers to all my questions and more. Christina was wonderful and helped me switch from traditional braces to invisaline! during my first appointment/consolation we decided invisalign was right for me and everything from taking my braces off, getting the molds for my invisalign and retainers was done that same day. The lady who made my retainers was also super helpful, she made sure everything fit properly and i knew how to put in and take them out before i left the office. i’m truly impressed with this team. everyone i met that day from the lady’s who checked me in, the lady who took my x-rays to Christina were truly welcoming and helpful. I’m so happy with the choice i made to trust Smile Doctors to help me continue my orthodontic journey!”
“Thank you so much Meghan for everything you did making this experience so smoothly! I have never been so happy to get my permanent retainers off, we fought through the pain, but I know my teeth are going to be so beautiful once I’ve completely the Invisalign. I cannot wait to see ya’ll in May 🤍✨ thank you all for everything you do!”
