Why choose Fisher Orthodontics?

Complimentary Initial Exam and Follow-up

Your first exam with Dr. Fisher is complimentary and obligation-free. At this visit, the patient’s orthodontic needs are assessed and treatment options discussed. If the patient is too young for treatment, or treatment would be more effective at a later time, the person will be placed on a four- to 24-month recall for follow-up.

During these recall visits (also at no charge), the teeth and jaws are monitored for developing problems. With this approach, you can have peace of mind knowing your child’s needs are being monitored without your having to worry about cost.

Honesty and Integrity

Our promise is to treat your child as we would our own. What exactly does this mean? We will only recommend treatment that is needed and at the most appropriate time. If something can be more effectively treated at a later time with a more reliable result, then that is what we will recommend.

Many parents get concerned about the appearance of their child’s teeth at an early age, when gaps and alignment problems are common. Many of these issues are part of normal development and may not require treatment, or can be more effectively treated later, when more teeth are present.

Education and Experience

Education and experience matter in orthodontics. Dr. Fisher is the only orthodontist within a 100-mile radius. To become an orthodontist, one must complete a post-graduate orthodontic residency after dental school, which is an extremely competitive process.

This training is unique to orthodontists, who must by law limit their practice to orthodontics. Orthodontics is all we do, so we can focus on getting the best possible result for you or your child.

Sometimes, due to poor growth, breakage, or lack of patient cooperation, alternative approaches need to be taken to ensure a quality result. Years of experience treating patients in residency and practice have given Dr. Fisher the necessary “bag of tricks” to handle a variety of problems, should they arise.

Please browse our Before and After section for a sample of cases we have treated. In our office, we not only strive for excellent aesthetics but functional and stable results that can’t be seen in pictures.

In-House Diagnosis and Treatment Planning

Following a discussion with the patient and parent, and a complete exam and records (photos, X-rays, and impressions), we are able to make an accurate diagnosis and offer a treatment plan that is most appropriate for you or your child’s needs. We do not send the records out for someone who has never met or examined the patient to decide on the treatment your child should receive.

This is important, because we need to reassess treatment progress at every visit and address issues as they arise, if need be.


There have been many advances in orthodontics that allow us to treat patients faster, during fewer visits, and do things never before possible. TADs (Temporary Anchorage Devices) allow us to complete movements without affecting surrounding teeth. They can also be used to reduce the need for patient cooperation (rubber bands), and even prevent surgical procedures that would have otherwise been necessary. We don’t use them in most patients but if necessary, they are very effective.
