After I had a minor stroke, she was the Dr who stepped up to try to develop a more complete picture of what happened, and why, through a series of studies and tests. I feel that she sees me as an Individual rather than just another body who has shown up In her office. Would definitely Recommend her for anyone needing a cardiologist.
