"I went in nervous and a bit unsure of what my options were and if I’d go through with treatment, from the moment I walked in the door to the time I left was an amazing experience! The staff were very welcoming and knowledgeable. Christina was aaamazing and informed me on all the options available for me and what worked best for me! I’m glad I made the decision to go with this location"

“What an amazing office! The staff here just makes you feel so welcomed. My son loved everyone. We were educated on benefits we didn’t even know we had. The entire process from the start has been so smooth and effortless. My son was very nervous at first but the entire team made him feel comfortable. During his banding appointment Courtney was SO gentle and patient with him. He absolutely adores her! Thank you Dr Adcox and team for helping my son take steps towards a confident smile!”

“While we got off to a rocky start with everything, this office has really taken the time to address any concerns I have had and educate me about the braces process. We have 2 kiddos in baces with another going to start treatment in about a year, the office has been affordable with great monthly plans and multi-kid discounts. Definitely worth the time to check them out. Thank you Yasmine for taking the time to address any concerns I had and explaining things to me. When a business genuinely cares and takes the time to address your issues it really does say a lot out the company. Thank you again!”
