Rating Feedback for Dr. Moss (2572095)

The rating:
'Rude. Arrogant. Wouldn't trust this guy as far as I could throw him. Took my wife off all her meds and said depression was not a disease. He has some issues. I think he has the right idea about over medicating but he goes about it completely the wrong way.'
