Healthgrades allows anyone to launch a personal attack on any doctor and they will post false reviews as long as the person has a valid email address. They will not allow doctors to respond to negative reviews. Instead, they advise you to get more patients to post positive reviews so that patients are forced to give their email addresses to them for their use. Don't bother trying to contact them because it's almost impossible to talk to anyone in charge. They basically don't care and feed on negative reviews to generate more business for themselves.
