Our Practice


To make your journey to optimal dental health as comfortable as possible and to answer all your questions along the way.

Our philosophy is to deliver "optimal" dental care to each and every patient that enters our practice.
We believe each person has the ability to control their dental destiny and we will help you take charge of this aspect of your life. We desire to develop a relationship with each one of our patients so that a great understanding can occur as to "why" we develop a dental disease. It is so important to understand because our practice is grounded very heavily in true "preventative" dentistry. Only when we determine the "causes" and control dental disease can we go on to correct the problems and feel we will get longevity of the results.

There is one very important aspect of our philosophy, you much "choose" to become healthy. This is why the "understanding" must become internalized. We cannot tell you how healthy you can be; we can only help you to understand. So sharing of your information, education, and informed decisions are at the core of our philosophy. 

Our goal is to help you to keep all of your teeth, for all of your life, and to achieve this with comfort and maximum esthetics, yet minimal anxiety and expense. Together we will explore and examine your teeth, gums, and joints, and create a lifetime treatment plan. We will use full mouth x-rays where necessary, molds of your teeth, and pictures of your teeth. We will review your past dental history, or past records and x-rays, in order to obtain a comprehensive understanding of your individual situation. Only in this way can we create a careful diagnosis, which leads to an optimal treatment plan.
