If you have an appointment with Dr Barnard Greisman, CANCEL IT.
The guy is the most disrespectful, insensitive, and unhelpful doctor I have ever met. He has plenty of sarcastic jokes about your body and does not have anything useful to tell you about your health. I want to accuse him of being unethical and a pervert, but there's really never going to be proof of that because he just plays with your emotions. Overall, he's just a lousy doctor. 0/5 stars.
Don't just take my word for it, look at the doctor's review at Ratemds (google it)
