I was quite shocked to read a negative review for this dentist. I am glad I read it after both my husband and my son had root canal treatments in her office. Each time we visited we found her to be gentle, caring and completely professional. She always took a moment to ask what my son was interested in and how well he was doing at school. Our family has had a total of three POSITIVE experiences and three successful procedures, 2 for my husband and 1 for my son. Dr. Nielsen explained each step and was very kind. Her staff is wonderful. Her assistants are kind, cheerful and know exactly what they are doing. I called around to get prices and this office had reasonable fees, on the lower end of the scale for specialists in the area. The best thing was that this office actually called my insurance and got all the info they needed to give me an accurate estimate before we came to the visits. I travel for business and often refer to the user reviews when booking hotels on-line. When I find a negative review for a wonderful hotel (a hotel that I have already used) it reminds me that, as in all things, your own attitude is the best indicator of the type of experience you are going to have. Perhaps that explains the other reviewer.
