About Our Clinic

We treat our patients as our own family. Our first and foremost focus is patient safety. We take sterilization, infection control measures and cleanliness very seriously at our office. Our infection control and sterilization includes special filters and chemicals to protect as biofilm. We use 3 autoclaves in addition to chemical and/or UV disinfection prior to sterilization. We use a 3rd party testing agency as the quality control to make sure our sterilization is effective.

We use the latest in the state of the art in technology in our office including lasers, 3D scanners, 3D printers, piezosurgery units, L-PRF, and advanced monitors for IV sedation.

We use digital x-rays and the latest 3 D cone beam CT scan technology to minimize x-ray radiation by as much as 90%. We do not use amalgam (mercury) in our office and never have used any chemicals to process traditional x-rays (we were digital from the beginning of our practice).

We started our practice in 1999. In 2010, we purchased the practice of Dr. John F Armstrong who practiced in Falls Church for over 33 years. We also merged our practice with Dr. John Deutsch- Periodontist who practiced in our office until 2012 when he retired after over 40 years of practice in periodontics.

Our office files dental insurance claims for those patients with dental insurance and we accept dental insurance.
