    After years of mishaps with dentists I finally found the perfect dentist; Dr John. I highly recommend him to everyone I meet. I even have family members coming from Albany NY to have him fix what others have done. The office itself is extremely clean and that means everything. The wait time is less then the allowed time on this site...I've never had to wait.
