I have never seen a Doctor Who spent so much time. Listen, carefully explained everything in detail and was absolutely a delight. I would highly recommend her. The best doctor I have ever seen.

She didn’t see much concerns for auto immune, but still offered to do labs just incase. Nice office staff!
