My complaint is that no one listened to us during my sons, Mark Edward Livingstones stay at this hospital. As a result brain damage was caused through the arrogance of Dr. Harold Hoffman. After all, what did I we know, we were only his parents.We kept warning the different levels of doctors of our sons low tolerance for drugs, but we were never ever listened to. There are huge consequences when parents are ignored. My son was damaged permanently during his stay at Sick Children’s Hospital under the “care” of Dr H. Hoffman
