Dr. Margraf performed my baby's autopsy. She lied to me and my wife about our baby's cause of death to protect Cook Children's hospital where our baby boy died. The hospital was at fault, but Dr. Margraf intentionally misled us about what caused his death, lying by omition, carefully avoiding the blood infection that the hospital gave our infant son, all to shield the Cook Children's from liability. If I could give zero stars I would. Dr. Margraf cannot be trusted.
