I highly recommend Dr. William Barrows group in downtown Chicago. His entire group is great but I KNEW that Dr. Barrows was special when my son had an episode where he passed out (he must have been around 8 months old). He was teething and my husband and I gave him some homeopathic stuff that was recommended. I called Dr. Barrows, but my husband I rushed my son out of the house and took him to the hospital. When we got home, according to our caller id, Dr. Barrows called at least 20 times.
Our son was okay and thank God all testing went well. He has never had an episode like that since and that was over 2 1/2 years ago. My ob/gyne recommended him to us because that is where he takes his little ones. Dr. Barrows is affiliated with Northwestern Hospital.
He's fantastic!
