After over 19 years of working together as dentists, they still share the same passion for creating beautiful and healthy smiles. Their shared vision for Washington Dental Associates and Smile More Dentistry has materialized into an exceptional dental experience for their patients. Each is a unique dental office where you will feel comfortable, well taken care of and safe.
Another passion they share together is their love for each other and their five children. Their weekends are spent watching their sons’ soccer or baseball games - they have never missed one yet. When they are not in the office working, you can find them on the slopes skiing or the Hudson River boating.
