    - in Monkton, MD |

    During my first visit with Dr. Brennan I learned more true facts regarding my heart condition than I gained from my cardiac surgeon, who performed a triple by pass and aortic valve replacement or my prior cardiologist. She is extremely thorough, immediately performed needed tests, reported the results of the testing within hours of testing, made a further referral to check other factors of my condition and called need RXs. She is truly the best doctor I have ever worked with bar none.
