I've been seen in your office before and this was part of the reason I chose to go back for Implant eval. I have always been treated very well! Everyone was smiling and friendly from the office staff to hygienist to the MD. I felt very comfortable and welcomed back. Thankyou

Dr shoemaker in the staff are completely professional friendly and make a possibly scary event a lot better. I have a huge anxiety problem with this kind of work, and they treated it in the best way without being condescending and all.
