About Us

When it comes to choosing a dentist, we know that you have options. Personalized, caring, meticulous and comprehensive care is front and center.

We are acutely aware and sensitive to the anxiety that the dental office and dental care creates in many people. Our office was designed with exactly this in mind and the result is a dental office that is calm, soothing, warm, and tranquil. Indeed, our office is specially equipped with a waiting room that is sound deadened and more like your living room than a waiting room. We also have specially equipped our dental clinical area with ultra quiet KAVO electric handpieces that are 90% quieter than traditional air driven handpieces.

Here are just a few things that make our practice unique:

Care and Commitment

From the front office to the exam room, our practice is made up of professionals who take your health very seriously. Using state of the art equipment designed with safety, efficiency and maximum tranquility/sound control we are able to offer a full range or services and treatments.Your safety and comfort are our priority.

Personalized Service

At our practice, you aren’t just a patient. We take an interest in you and your oral health needs. We think you’ll find a friend in your dental professional during your visit!

Easy Access to Dental Care and Information

Your time is valuable to us, and that’s why we offer extended office hours on select days, dental appointment reminders, and a quick turnaround on calls and appointment requests. You get the Doctors direct off hours emergency contact information. We are happy to answer any questions or concerns in the office, over the phone or via email.

Comprehensive Dental Care in One Location

At Georgetown Advanced Dentistry, we are qualified to handle all aspects of your care, so you are always surrounded by personnel that are fully trained and deserving of your full trust and confidence. If we must refer out, we promise to send you to carefully selected colleagues who apply the same professional principles in their office that we do in ours.


We are particularly sensitive to the fear and anxiety that accompanies visits to the dentist. The office, staff, hygienists and doctors have been carefully selected and trained to maximize a sense of comfort, safety and tranquility. We respect and understand that many patients experience dental anxiety. At our office, we do everything we can to make sure that your experience is as relaxing as possible. By communicating clearly what you can expect during your treatment, we are often able to alleviate dental fear. We encourage you to bring headphones and music to listen to during your treatment and ask us about dental sedation options.

Honesty and Affordability

We know that the cost of care can be confusing. In addition to offering a number of in-office payment options to fit your budget, we also give you up-front cost information on your treatment ahead of time. We are in-network with a variety of insurance plans, and we offer various forms of financing with credit available in time frames that fit your needs. Our team is happy to help you navigate your dental insurance and alternative payment options.
