Dr. Susan Orenstein and her staff are absolutely wonderful! They are on top of current medical research and work well together to reassure the parents and the patient and to present information in a manner that lay people can understand. We always had her undivided attention when it was our turn to see her. There was never a very long wait. They are always available by phone should an emergency arise. We feel so fortunate to have been referred to Dr. Orenstein and to Children's Hospital of Pittsburgh.
