About Us


Starts Here

We welcome patients of all ages, abilities, and backgrounds to join our dental family in Ashburn, VA, and discover the benefits and comforts of modern dentistry. We offer a full range of preventive, restorative, cosmetic, and general dentistry services to promote good dental health and inspire happy smiles every day.

General Dentistry

With a gentle chairside manner, we offer routine exams, pediatric dentistry, and a host of procedures to treat cavities and periodontal disease.

Cosmetic Dentistry

Transform your smile with our treatments to whiten teeth, hide chips or cracks with veneers or dental bonding, or rehabilitate with a smile makeover.

Restorative Dentistry

One of our specialties is to replace tooth loss and protect and reinforce the function of your teeth with crowns, implants, bridges, or dentures.

Orthodontic Options

Metal braces are a thing of the past. Now you can straighten your teeth with more discreet alternatives, like clear braces or clear aligners.

Advanced Technology

We utilize innovative tools to assess and care for your TMJ needs to relieve pain. Treatments include oral appliances, bite modification, and more.


We can help you attain a renewed, younger-looking appearance with our noninvasive skin rejuvenation options to diminish facial lines and wrinkles.

Got down to the cause of a problem I was having. Very good experience overall. As usual.

Dr. Claustro, Aubrey, and the hygienists were amazing! You can feel that the warm, family friendly, welcoming environment my family and I enjoyed is who they are. This is only matched by the high quality care, attention to detail and professionalism I experienced. You can tell they care about each person who comes through the door from her youngest patients on up. I would highly recommend the whole family giving this dentists office a try. You will be glad you did.

Had a cleaning today with Michelle which is always a pleasure, and met Dr Claustro’s new associate, Dr. Argawal. She was very kind and thorough.
