I have been going to Corey + Then for well over ten years, receiving top notch care each and every time. My peridontist is a genius! (They all are.) Their entire staff is the best I've ever seen. The office is amazingly efficient and caring.

Very professional. While I wasn’t particularly excited about getting a tooth pulled, Dr Then showed me and clearly explained why it was necessary. I would definitely recommend this practice for periodontal work that needs to be done.
