"4 out of 5 stars"? What mathematical equation are you using Yelp?? It's simple division. I see TONS of zero star reviews with VERY bad experiences. I have to question Yelp on this one, which I have normally trusted. Yelp, please respond about how this unscrupulous dentist is getting rated a "4 out of 5 stars", when the math doesn't add up to that #?? PAID ADVERTISING BY THE DENTIST TO GET THIS SKEWED RATING???
