The trust our patients give us is a gift we appreciate and value. We strive daily to earn and keep that trust. We faithfully provide exceptional care and respect to all of our patients. Appletree Dental’s goal is to make each visit to our office a pleasant, comfortable, and comprehensive experience.
Our doctors and hygienists recommend visiting every six months for preventative care. For our patients with specialized treatment requirements, we often recommend a more frequent visit for preventative care. You can expect great communication with your doctor and hygienist – we will discuss all options available for treatment as well as discuss a written treatment plan that you can take home with you. We do our best to ensure you have as much information as possible about your insurance policy that your employer chose for you.
