I was looking for a mercury free dentist and had one bad experience already, so was a little concerned. A friend recommneded this dentist, and I trust her. Unfortunately, she can zone out and escape through meditation and I didn't have that luxury. I found him to be rushing through the whole thing, with horrible bedside manner....I asked him to explain what he was doing, so I could understand, and he couldn't be bothered.... (I had a root canal, so this was a long a arduous process) and quite frankly it felt like going to Attila the Hun. Lucky for me, in the last 2 months, I have found a wonderful mercury free dentist in Los Gatos now and am super happy, Dr Richard Evans.
