We waited an hour in the exam room before the doctor entered. We were only able to spend 15 minutes with the doctor since my daughter needed to eat lunch and get ready for school at 1pm. I intentionally scheduled the appointment for 10am so we had ample time for the doctor. We didn't leave the doctor's office until 11:45am.

February 16, 2018 6:00 PM

After a very painful experience with Lurie Children's Hospital, we started to see Dr Heneghan. She is really great, takes her time to listen to us and answer all our questions.
