Best ENT I have seen! Both Dr. Vaughan and Kathleen Low are excellent! Very knowledgeable, thorough, and up-to-date with the state-of-the-art. Both take lots of time to explain everything very well, and it's always nice to talk to them in general. I highly recommend both of them, especially for sinus-related issues. They even have CT in the office which is very convenient, if needed.

Dr. Vaughn is so knowledgeable, conscientious, and good at what he does. The staff are always professional and courteous, and the office is impeccable. I feel grateful for having been referred to CSC when I was in need and can't thank their team enough for their care.

I highly recommend Dr. Vaughan and his staff. I've seen a number of ENTs and Dr. Vaughan is best for me. I have seen him for a number of years with a difficult case. He brings broad experience to bear on recommending treatment plans that are appropriate (not too aggressive or too mild). He discusses his findings and recommendations. And he will answer all of my questions thoroughly in an approachable and friendly manner. His staff is also very cordial and helpful.
