Dr Santos is a fantastic dentist! Dr. Santos's assistant, Rachel, is wonderful as well. Together, they both make a terrific team. As for the office, it's clean, modern, and in the heart of city (Union Square). Dr. Santos' office is filled with lots of high tech equipment. However, this may be the reason why her fees appear to be somewhat more expensive than other dentists. In fact, this is probably the only problem that I have with Dr. Santos' practice. Otherwise, I highly recommend her practice.
