He very good with filligs and technical work. He loves expensive gadgets and tests. These hi tech tests, which never seem to find much of anything, make his services rather expensive. My MetLife dental insurance never covered much more than 60-70% of the bill. With tests, a typical 6-month cleaning bill would run $160-$290.
About Hygienist: He always hires cute female hygienists and had been through several lately. I am not sure why his hygenist turnover is so high.
