Meet The Team

Dr. Geith James Kallas

A pioneer in modern dentistry for over 25 years! Dr. Kallas earned his Doctor of Dental Medicine (DDS) degree in 1989. In 1993, he graduated from the Howard University College of Dentistry postdoctoral program. While there, he completed his internship at the District of Columbia General Hospital. Since then, he has pursued inter-related continuing education courses, focusing on becoming a premier provider of advanced and comprehensive aesthetic dentistry.

Dr. Kallas realized early in his career that the technologies, materials, and procedures of general dentistry weren’t reaching the high threshold of quality care he had established for himself. He quickly learned that the techniques and materials used in cosmetic dentistry were stronger, healthier, and could also be applied to general dentistry for better, longer-lasting, and more attractive results.

As a result, he pursued advanced training at the Las Vegas Institute (LVI) for Advanced Dental Studies, a leader in providing aesthetic and neuromuscular dentists with the high level of skills necessary to successfully practice the art. Today, he is among only two percent of dentists in the world to have achieved this level of training.

A proponent of advanced training, Dr. Kallas makes sure that his dental team receives the most advanced dental education. Hygienists, assistants, and administrative personnel have been trained in the latest clinical techniques. Education is a continuing mission of the team, and they will do everything possible to ensure that you receive the best personalized care.

Named the Virginia “Dentist of the Year,” Dr. Kallas understands the difference an incredible smile can make in someone’s appearance and confidence. He frequently gives interviews about the latest advancements in dental technology. He has improved thousands of smiles in his practice, making him highly skilled in the art and science of smile design.

Dr. Kallas is distinguished in the U.S. and internationally for excellence in dentistry and for his contributions to his community. His achievements and associations include:

  • Top Dentists Consumers’ Research Council of America
  • Best of Vienna
  • Best Dentist of Vienna, VA
  • US Commerce Association
  • US Local Business Association Best of Local Business Awards
  • American Council of Dental Sciences
  • International Association of Dentists – The Leading Physicians of the World

He also donates his time and expertise to the WIN Foundation, which raises money and awareness for battered and homeless women.
