PS: I spoke to a couple who both happen to be doctors here in Phoenix.
They are parents of a kid who goes to school with my son. When I told them your grandson's story, they knew the doctor your family had at Barrow's. They said he is the best in the world at this type of surgery and he gets a lot of tough cases to consider. He is extremely talented and performs corrective surgery when no other doctor will. And, he has terrific success doing so.
They also send their best to you and your family and are very happy for your grandson's recovery.
