This is my business. I'd like to submit an update.

We understand that everyone’s orthodontic needs are different, and we pride ourselves on creating custom, tailor-made orthodontic solutions for each of our patients.

What do clients have to say about you?

Rebecca C. - Dr. Casey and her entire staff could not be any nicer! My daughter always looks forward to going to her orthodontist appointment. I could not be any happier with the care she is receiving.

Colleen M. - An all around outstanding experience! Dr. Casey was very knowledgeable, patient, and friendly. She took the time to explain the procedure to me and my son. She made sure she addressed all of our questions, regardless how relative they were to what was going on during the current office visit. Her staff is also very friendly and eager to make every patient feel at ease. I have 2 more that need braces and we will definitely be going back to Dr. Casey!

Beth Ann C. - I have 4 children and have been with Dr. Casey since 2006. My last one is now in braces and I have to tell you it’s bitter sweet knowing our visits are coming to an end. When the process is completed you leave with two things a great smile and fond memories of a friendly and compassionate staff. Thank you all for making this a painless process for my kids.
