He has all the latest technology and performs superb work, though it comes at a high financial cost. He's performed crowns, fillings and an inlay (using CERAC) on me, and they've all been virtually painfree. The dentists to whom he's referred me for wisdom teeth extractions and root canals have also been first rate. He's very good at explaining the options and the procedures though he can be very outspoken / non-PC on non-dental matters - I'd hate to work for him!
Wrt the front-desk they're mainly friendly and all greet you by name as you walk around. I tend to pay cash the whole time and then get reimbursed by my insurance company, and I occasionally have hiccups with the reimbursement. Whose fault that is I don't know, but the dental office are very quick to step in and call the insurer when there's a problem.
The facilities are very modern - TV's and cameras everywhere, and all the staff communicate using earpieces - very high tech!
