Care Philosophy

This content was provided by Dr. Morganstern "As a parent, I understand that you are concerned enough about your child's health to come to a subspecialist. You want a professional, informed opinion from someone you trust. I am neither an alarmist, nor a "sugarcoater." I will spend as much time as necessary so that you walk out feeling confident that you are in the right hands. Working in an academic children's hospital gives me the advantage of having many other pediatric services and subspecialists available as necessary."

Patient Comments (4)
Sayville, NY |
Dr. Morganstern offers a refreshing combination of clinical expertise with good bedside manner. He treated our child's very complex presentation following a critical illness. He spends time with patients and parents explaining his rationale and thinking, while answering all questions and concerns. I would recommend him without reservation, and feel very comfortable entrusting him with my child's care.

We went to Dr. Morganstern with our first son who is now 22 months old when he was an infant after being told repeatedly by his pediatrician that he was just colicky after being treated by Dr. Morganstern my son was a new happier baby! When my now 8 week old was mimicking the same symptoms of his older brother we went straight to Dr. Morganstern! He has a great bed side manner & never rushes us. We highly recommend him
I highly recommend Dr. Morganstern! He is a consummate professional with an exceptional bedside manner. I never feel rushed during our appointments; he always takes the time to thoroughly answer all of my questions (and definitely goes above and beyond in the medical care of my daughter).

Our infant daughter was told by several doctors that she was simply colicy and there was nothing that could be done. Dr. Morganstern and his fantastic staff (especially Janet) took the time to listen to our concerns and observe her discomfort. Within a month of his care and diagnosis our daughter went from tears to cheers. Dr. Morganstern is a kind, caring intelligent man with A+ bedside manner.
