Dr Brennen and his staff are very friendly and listen to everything I had to say

He took the time with me to do a 6 min walk test for oxygen levels and shortness of breath. He reviewed my CT results and showed me the comparison to previous tests.

I would tell him that he is thorough, he's very bright, he listens fully to what you have to say and he's very extremely well at explaining and making sure that you know what's going on. He also was encouraging to follow up with me. I really, (INAUDIBLE) a very good doctor. Thank you. Bye.

He is knowledgeable, sympathetic and goes out of his way for his patient. Always made time for me when I needed him

Dr. Brennan was very thorough, respectful and told me exactly what the procedure would entail. He also followed up with a phone call to ask how I was doing and let me know that it was not the metastatic melanoma that I previously was treated for and that he called Dr. Fidias and let him know. He also told me that it may take up to 6 weeks for the lab to grow the culture that he biopsied. While I was in recovery he also let my wife know how the procedure went and what he saw and did to put her mind at ease. We would highly recommend Dr. Brennan to anyone looking for a Pulmonary doctor.
