I've been going to Dr. G (and his son Dr. Joe) for over 15 years. Until recently, I've been very satisfied. The office is small, but impeccably neat and clean. Over the past several years, many upgrades and improvements have been added (like digital x-rays). The entire staff is exceptionally nice and friendly. Having never really liked going to the dentist, they recognize this and have taken extra care over the years to make me comfortable (not switching my hygenist, fully explaining any procedures, etc.).
Recently, they have bought/opened another practice in Wayland. I'm happy for them, and they are doing well, but I feel it's spread the two Dr.s a little thin, at least in the Boston office. Neither doctor was available in the office at either of my last 2 appointments, regular 6-month cleanings (so it will be over 1 1/2 years between having the actual dentist see my teeth!). Hopefully, they are still just working out the kinks of opening a second office and this will fix itself in the future.
