My visits with Dr. Nathanson were frustrating on a number of levels.
Although she seems like a skilled dentist, her staff isn't trained well (as evidenced by her constantly yelling at them to do things right.) For a patient, it is very discomforting to have your dentist yell at her staff as they have their fingers in your mouth.
Also, her prices are at least 25-30% higher than comparable dentists in the area (whose rates I checked after having work done by her). Her work space, while functional, is old and dirty--she is, I hear, looking for a new location.
Overall, based on my general experience, I cannot recommend Dr. Nathanson.
