I am so fortunate to have Doctor Marshall as my Cardiologist! She explains things so that I can understand what is really going on in my body. She truly cares about my well being, not doing procedures when they may not be necessarShow morey. Unfortunately there are some physicians that aren’t as caring and honest as Doctor Marshall. I was referred to her from a nurse that knew her years ago, working in another city at another hospital. I consider myself very fortunate.

Dr always provides a safe place to be heard with my health concerns. She is pleasant in her delivery of prognosis and diagnosis, as she is very considerate in not injecting fearful outcomes of any situations presented. Not only is she a “doctor”, she is a healer because of her approach with western medicine..
