John Brennan, MD

Dr. Brennan seemed to be a very concerned health provider, listened to me very carefully and has taken care of me. Thank you.

Very interested in my case. Comprehensive in his review of my experience. Clear about options and future follow up.

Dr Brennan knows his stuff, and listens.

As it was my first visit with him, I brought my records from previous out of network providers, which he took the time to look through as we discussed them. He listened carefully and openly. I was very pleased with our interaction.

friendly caring very informative felt so much better after the appointment

I have already told them that Dr. Brennan was fantastic. He listened, went over test results with me, and came up with a good plan to treat my condition. I didn't feel like he was rushing to get through my appointment. He was very patient and kind.

If a friend is in need of a pulmonologist, Dr Brennan would be my first recommendation.

Definitely recommend.

I am very happy with all my team at Core.

They are good
