your comfort is our top priority

We try to make your visit as comfortable as possible! You will be greeted with a smile when you enter the office. In the waiting room you have access to a variety of magazines, movies, and a Playstation that you can use at your convenience. There is also juice or water available in the reception area at the beverage bar.

From the big screen TV to the corner fireplace, we have made every effort to create a comfortable “at home” atmosphere to put you at ease.

While you are in the treatment room you have the choice of watching an entertaining DVD while you receive treatment (DVD ratings range from G to PG-13). Our goal is to make you as comfortable as possible while providing quality dental care. All of the treatment rooms are equipped with the latest technology so your oral care needs can be met in a comfortable way.


Patient-focused care

We try to give each patient individualized attention and care and strive to see each patient on time. We cater to emergency patients, those who are in pain, or have broken teeth, and schedule them the same day they call when possible. This occasionally puts us behind schedule. When this happens, we give a courtesy call to let later patients know we are behind.
