When your first introduction to pediatric dentistry is in an emergency (an autistic two year old with an abscessed tooth) you want to make sure you choose someone good. We chose Dr. Ginsberg's practice based on recommendations from friends and we haven't regretted it in the least. We actually haven't ever seen Dr. Ginsberg. We first saw Dr. Kohn and later Dr. Simon and have really liked both. Dr. Simon has a good rapport with kids (as do all of the hygienists). She is able to put my older child's nervousness to rest and deal in a straightforward and respectful manner with my younger child--who doesn't make it easy to do so!
Their office in Catonsville is quite nice--there is a climbing/play area for younger kids and video games for older kids and a good magazine selection for grown-ups (no small thing). It is sometimes difficult to get an appointment because they are so busy, so call well in advance of when you'd like to see them if possible. They also have an office in Ellicott City.
