I don't normally write reviews either, but my dental experience with Martin Williams at Sierra Dental was by far the worst of my life! DO NOT go there unless you want many unnecessary procedures along with a hefty, and surprising, out of pocket expense. They even have a mean little woman who comes in, presents you with the bill, and threatens you that you need to pay this outrageous amount before leaving the office. I do have decent dental insurance & never had "bad teeth". But according to Dr. Williams my teeth were so awful they required "special" treatments (which apparently were not covered by insurance). He seemed confused & incompetent from the start - I should've ran then. I will drive the 45 minutes back to see my old dentist - who says my teeth are perfect. I wish i would've read these reviews before going there!I feel so scammed!!!
