Dr. Mortimer expects to be treated like a god. He wants and expects no questions from a parent and refuses to answer them. He made a mistake in a diagnosis and when this was pointed out to him he became exceedingly defensive and angry and refused to explain why. His explanation, it was simply to simplify a complex situation. If you are an educated professional take your child elsewhere. If you have no education and will worship him and don’t mind a misdiagnosis, he is fine.
