I've seen Dr. Bergman twice for root canals, the last and final time for one root that failed. He isn't holistic at all and kept wanting to put a metal filling in my root canals, which I refused. I was clear with him that I only wanted bio-identical composite fillings in them, and had driven two hours to a dentist who could provide them for me. When he had to redo one of the two root canals, he put in a composite filling that is not bio-identical and I had a tiff with him during the middle of the process.
His attitude was so dominating and disregarding that I felt overpowered. I wondered if this is his typical way of treating female clients, and I thought of my friends who report being raped by dentists.
Both times I found him to be very deficient in customer service skills. I had numerous power struggles with him related to parts of my treatments because he refused to give me critical information and give me choices when there were opportunities, and generally disregarded my preferences and feedback. When I confronted him about his poor "chair side manner," he said he'd rather be my dentist than my friend. It's obvious he can't do both.
Look elsewhere for an endodontist.
