Rosie was very nervous prior to visiting the dentist but after her consultation she said she felt very comfortable there and would come back for her procedure without worrying. She loved the doctor and the dental assistant. All the employees spoke directly to Rosie, rather than asking me (her mom) all the questions. My kids really appreciate being spoken to and not spoken about.
