I had to go ahead and write this after seeing so many new and negative reviews. I had an incredibly negative experience with Dr. Charles Hayes Mann of Mann ENT in Cary NC. I have noticed that his reviews were poor at best and he now had 85 reviews on google for a score of 4.5. Interesting that they were all rently written and sound the same. This guy is a complete disaster. I have been a=caused problems by him that other dr.s either dont ant to touch or cant fix. They double billed my insurance and myself. The RTP region now has many quality Dr.'s to choose from. Do not waste your time or money here. I would love to hear of anyone getting a class action suit together or having a personal injury attorney look into this guy. What a scumbag you are "Dr" Charles Mann.
