My experience at Deer Valley Dentistry has been by far the worst! If I was able to give negative stars I would. They wanted me as a new patient and I agreed to come for an appointment at their practice because they promised me that the appointment was paid for by my insurance and promised that there would NOT be any out of pocket expenses to me. Well, the staff at Dr. Jay Spiegel's office simply lied when they said the insurance would cover the appointment, so they could convince me to become their patient. It has been approx. a year since the appointment and I am still getting billed by Dr. Jay Spiegel. The last bill was just under $100. I have asked to talk to Dr. Jay Spiegel himself but have been denied to talk to my own doctor! The receptionist Courtney simply ignors the patient's requests, she says she will take care of the issue but doesn't follow through and doesn't call back. The Office Manager Carmen was extremly unprofessional and laughed at me when I asked to speak to the doctor. Deer Valley Dentistry has put no effort to resolve the issue and continiously sends new bills! Go to another dentist if you want to be taken care of properly.
