Ready to Learn About Your Options?

Schedule a no-pressure orthodontic consultation with our team. We’ll listen to your concerns, evaluate your smile, and explain whether treatment may be helpful.

There is no obligation to begin treatment. Our goal is to make your first visit as smooth, comfortable, and productive as possible.

Before your appointment, our team may review insurance information and help with any applicable copay, records fee, or claim-submission requirements. When possible, we may also gather information in advance to save you an additional trip.

During your visit, you’ll meet with one of our doctors and our experienced team. We’ll explain what we see, answer your questions, and walk you through any recommended next steps. You’ll leave with a clear understanding of your options, whether treatment should begin now, later, or not at all.

Kind words from our patients

My daughter goes here and couldn’t have asked for a better orthodontist. The staff is always friendly and answers my questions no matter how silly they may be. They did my daughters braces and couldn’t be happier.
