Whitney Yahn and Great Lakes Pediatric Denistry is probably one of the most incompetent and unprofessional practices of any "profession". My daughter missed an appointment due to a medical emergency, one that required two trips to the emergency room. They will not reschedule, stating that we should have called apparently while in the examination room at the hospital. In discussing this matter, they were very rude, and lied to me regarding a number of matters, including their lack of decency in failing to simply return a phone call, saying that they left me a voicemail (It's easy to look and tell if a voicemail or even a return call were made.) Furthermore, the dental "work" (a spacer) fell out within a month of being put in, and she didn't even show any real desire to fix it.
