How likely are you to recommend Dr. Brennan?

(Select your rating)
Dr Brennan is a Dr that methodically communicates with great precision and care. A trait that is slowly fading in the industry. I was impressed by his bedside manner that immediately put me at ease. There is also a calming presence about him that made this last visit to the hospital a little more pleasant.
