Your first visit to our practice is entirely complimentary. During this free consultation, we provide you with digital photographs, panoramic x-ray, and a 3D scan that allows you to see a 3D simulation of your own smile in minutes! A huge value for our patients.

Once your treatment plan is ready, we go over your options with you, explaining everything in detail. Based on the final agreement on what you need done, we present you with all-inclusive fees, and no hidden charges for anything we agreed upon.

We accept and file most orthodontic insurance plans and offer in-house financing for payment plans. Our practice accepts all forms of payments, such as cash, check, Discover, Visa, MasterCard, and American Express.

Highly Advanced Orthodontic Practice with Commitment to Patient Education

Our top-notch practice embraces new technology, not just for the sake of looking elite. Acquiring the latest equipment, materials, and appliances, and providing our staff with extensive training, helps us to serve you in the most efficient ways possible.

We put our patients first and strive to exceed their expectations by carefully educating them every step of the way to beautifully aligned teeth. You can put your full trust in our orthodontic team; we recognize that some children would benefit from starting treatment later, or that other alternative treatment might be a better solution.
