Committed To Being The Very Best

Every day when we come to our office, we recommit ourselves to serving you to the very best of our ability. Then, throughout the year, we attend continuing education courses, explore the latest technology, and implement new procedures to improve our level of care.


We never double book appointments and we make every effort to run “on-time” because we know how valuable your time is. You deserve our full, personalized attention during each visit.

Dr. O’Donnell has a very experienced and helpful staff. In an area as transient as Northern Virginia, it is unusual to have employees that remain with a practice for many years. With such a loyal and dedicated staff, our patients become more like friends and family. We get to know you and there is a lot of one on one in this practice. It is not an assembly line. Dr. O’Donnell has patients that he has been treating since they were children that are now bringing their own children to the practice.
