Dr. Marshall is the worst dentist I have ever been to. My insurance company sent me a copy of the bill that Dr. Marshall submitted and I immediately noticed that he charged my insurance company for services he did not even perform. When confronted, he didn't seem to care. I would expect from his response that he has done this many, many times and seems to continue to get away with it. I would think twice before visiting Dr. Marshall. I would never return to him. If you do chose to seek services from him, be very wary about his unprofessional practices.
