Dr. Brennan is very down to earth. She is approachable and easy to talk to. I always enjoy our conversations which are not just about health issues but also what is going on in life.

Dr. Brennan is very data driven. I really like that she looks at all of the test results and even ask for more test results before coming to a conclusion. I feel like she's taking this seriously.
