She is amazing.
I love her bedside manners. I love that she listens to my concerns . Such a sweet personality.
Dr.Brennan was AWESOME in every aspect. She explained the three exploratory steps to get the answers for my medical issues. Dr. Brennan took her time and answered all my questions. I didn’t feel rushed but felt extremely comfortable. I left there feeling like I was in good hands with Dr. Brennan.
Shows concern for patient's condition.
Dr. Brennan was professional, friendly and listen to my concerns with being a new patient. I had my medical records released from the previous cardiologist from out of state, it was obvious that Dr. Brennan took time to research my history. Dr. Brennan staff was professional, friendly, helpful and extremely detailed. The front desk personal was detailed, professional and helpful with checking in. Office was extremely clean and welcoming.
