After a cleaning and sold on a crown for a chipped tooth, I got the worst throat then bronchial infection the same evening. I was sick for 2 week. The doctor has no assistant. He attempts to handle the suction and other patient care matters by himself. Most dentists I've been to have a qualfiied assistant to help. This explains why bits of broken filling went down my throat. I was additionally over charged for services beyond what the agreement is with Delta Dental and have yet to have a phone call returned after 4 attempts. I think Dr. Collard is skilled but his practice is lacking in a qualified assistant, adequate sterilization, and a nice front office person that returns calls and handles billing disputes promptly.
