He didn’t listen to anything I said, blew me off completely when I talked about pain, and told me to walk on a limb that is clearly injured and that 3 other medical professionals told me to stay off of. I wouldn’t recommend this guy to anyone. Haven’t ever been treated so inhumanly before in my life. Don’t waste your money. This guy shames the medical profession.
Very understanding and acknowledging professional!
He was an excellent doctor. He gave me a gel injection in my knee and I didn’t even feel the needle. I feel so much better now.
He is caring and professional - and he listens!
Excellent professional answers all questions
