Good at explaining signs and symptoms for future problem with tooth. Dr Mahn was very patient with his dental assistant who appeared to be new to the practice. She did a great job, too In explaining what she was doing.

I left very angry. He was the kind of dentist that make people afraid to come in. He talked down to me, made me feel stupid when I asked about a warranty on my bridge. Will neve go to him again.

He spoke maybe one full sentence to me, the rest to the very kind dental assitant, and was gone without asking any questions or offering any words of counsel about my teeth. I was frustrated that I did not feel cared for by him seeing as this exam was something I needed in order to get a consult (which I have already had) about wisdom teeth removal.

Dentist was cavalier about if I went to another dentist. He was demeaning and talked to me like a child. He interrupted me often.

Did not appreciate the Dentist attitude in how he approached my visit. He was short with his words, pushy and not friendly. Hes not the dentist I normally see and I do not want him in the future
