Mark Greene

Dr. Mark Greene was a fictional medical doctor from the television series ER, portrayed by the actor Anthony Edwards. For most of his time on the series, Greene's role was that of a mediator and occasional authority figure, and he was considered the main character of the series for the first eight seasons. Mark Greene, an only child, was raised by his mother, Ruth, and father, David. David Greene served in the United States Navy, and thus the family moved frequently.
