We always have a good experience but this time was exceptional. When my daughter was getting her echo, she was a little nervous. They played and sang music from her favorite movie Frozen to her. During the doctor visit we were able to include my husband through a video call. Dr. Zahka took the time to answer all our questions about returning to school during a pandemic. His nurse Danielle was amazing as always. We were entertained and had a great time which is something I wouldn't expect to say about going to the doctor.
