Dr. Robert DiValentin

Vienna dentist Dr. Robert DiValentinAfter practicing dentistry for 44 years it was time to sell my practice. However, I still enjoyed the connection with my patients and was not ready to retire. It was my great fortune to meet Dr Barakat and we began the transition of my practice to his.

The most special moment for me is the day I married my wife, Marybeth. Together we have shared our four children and thirteen grandchildren with another on the way.

One of the hobbies I greatly enjoy is fly fishing. My son, Michael, and I have been able to fish many streams together enjoying the beauty and serenity they have to offer.
