This is the type of Dr. you never want to see. I have Stiff-man syndrome that took years to diagnose but he would rather treat me as a mental patient rather than someone who is actually sick. Refused to refer to another Dr. Refused to answer simple question because I was a chronic pain patient! I wouldn't let this guy treat my dog!

I have never before seen such blatant bigotry from a doctor. Refused to provide refural after he said he would not treat me. Could not (refused) to answer simple question about medications. This guy should not be allowed to treat anyone!
He refused to refill scripts ive been taking for over 40 years before ever meeting me or running tests
