I absolutely love Dr. Westerfield. She is very thorough, took her time with me, answered all my questions, and came up with a plan moving forward. She has 1 of the best bedside manners I have ever had with a doctor. I would recommend her to anyone who needed a good cardiologist.

I had a previous commitment that morning and arrived early for my appointment. Everyone was very friendly and helpful and my wait time was excellent under the circumstances. I believe they got me into the exam room early and Dr Westerfield came in shortly thereafter.

Dr Westerfield is an extraordinary physician! She always takes time to listen and truly cares about her patients. She makes you feel like family. I have been her patient for over 15 years and couldn’t imagine having anyone else care for my cardiology needs.

Dr. Westerfield is ALWAYS at the top of her game. She even called my oncologist from the exam room due to a mutual concern. Obviously, she had read all of my test results from last week’s visit with my oncologist. Dr. Westerfield responded immediately to their conversation by sending me to the ED for further tests.

Was there anything that you feel was outstanding?
Dr. Westerfield was so incredibly kind. She asked extremely pertinent questions and, when I wasn’t really sure about my answer, she recognized my discomfort and reassured me that there was no right or wrong answer and not to be concerned that I wasn’t really sure. Dr. Westerfield made me feel comfortable about asking questions and readily answered, explaining anything I wasn’t quite sure I understood. I was overwhelmed by her friendliness, kindness, compassion, and respect for me as an individual, and, while I was relieved that she felt my heart was in good shape and that I was on a strong and healthy path for my heart, I was a little sad that I didn’t need to make a follow-up appointment! If I were to require surgical intervention at any point, I would be completely confident that I was in great hands with Dr. Westerfield!

Dr Westerfield is such an outstanding physician. I have had a plethora of doctors in my lifetime so I am a qualified judge. She is bubbly, kind, attentive, knowledgeable, and genuinely cares about my health. She never misses an opportunity to laugh with me and that is a FIRST in my experience. I recommend her to anyone in need of a Cardiologist. I even recommended her to a new patient in the waiting room who was searching for a new doctor.
