I am *Dr. Mark's patient for only a few months. However, she's a compassionate professional and I am at ease with her judgment.

Dr Mark is an excellent doctor! She seems to genuinely care about her patient and condition. She seems determined to find results. She has a great bedside manner - she is patient, informative and manages to make an uncomfortable condition easier to talk about. I have several doctors at west med and find her to be one of the best I have seen.
