Everyone, staff & Dr Westerfield were very helpful! I had written down the wrong time, for an hour later than scheduled, but Dr W took the time to see us anyway! She's always been a very compassionate, uplifting individual! Mom just loves her!

Dr. Westerfield is a very kind and explains everything she does during her examination. She listened to my problems and complaints and gave me advice on how to cope. She changed my medication and explained how to do it and how to follow-up with her in two weeks. The entire stff were excellent.

Dr Westerfield , in my opinion, is an extraordinary cardiologist. In the short time I have been seeing her, more has been accomplished and diagnosed than the 30+ years with 2 other cardiologists. Her thoroughness in explaining what is wrong or what needs to be done in lay terms is outstanding. I am so happy she was highly recommended to me.

Dr. Westerfield: (1) always makes you feel the center of attention (2) never presents a feeling of needing to "move along" to accommodate a time constraint (3) provides quality guidance for health problem options and resolutions beyond the scheduled issue (4) presents a broad focus that considers multiple health factors for a solution, not a narrow tunnel vision that may miss important contributing factors (5) does not use jargon in explanations, easy to understand and follow healthcare needs (6) creates the most genuine desire to seek out for concerns.
