Dr. Thoben has very nice support staff who took the time to explain all the charges to me. His office is located in the basement of a downtown office building, a bit dark and dreary if office environment matters to you. At the time of my visit, I had switched dental plans and was looking for a new dentist. I didn't get the feeling that Dr. Thoben welcomed my questions, and ultimately decided that I'd rather find a different dentist. Absolutely nothing wrong with my visit, I was simply looking for a new dentist and decided Thoben wasn't the right one for me.
