About us

Mission Statement & Practice Philosophy

We are dedicated to providing orthodontic care of the highest caliber in a relaxing, comfortable, and friendly atmosphere. We strive to provide exceptional service before, during, and after treatment to establish a lifelong partnership with our patients.


We treat all of our patients in a compassionate and understanding manner. We want our patients to be delighted with the service they receive and so comfortable in the surroundings of our office that they can, without hesitation, whole-heartedly refer their friends to our practice. This is not only the ultimate measure of success of an orthodontic practice but also the highest form of compliment to our efforts.


We create beautiful smiles, while helping our patients realize the benefits of increased self-confidence and an improved quality of life. We can accomplish this by identifying our patients’ concerns and anticipating their needs, so that Dr. Cook and our team can work in mutual cooperation with the patient. In addition, we work in partnership with other dentists and health care professionals to help ensure comprehensive care for our patients.

I can also be found in our clinic in the afternoon assisting Dr. Cook with putting braces on, taking braces off and all the appointments in between. One of my favorite things about what I do is getting to know our patients and families and developing those unique relationships. Outside of the office, I am always on the go!
