I do not know Dr Engelston but I am very disappointed with the service. I am a new patient and I called for an appointment. I am a physician who knows the effects of radiation and wanted a cleaning, but no xrays. The receptionist said if you don't want x-rays, you can call another office. In a regular hospital, we would never radiate a patient without a just cause, and without a patient having symptoms. I do not understand why I cannot just come in for a cleaning. Extremely rude and unprofessional.
