Editing Mark Greene (section)

==Character background==

Mark Greene, an only child, was raised by his mother, Ruth (portrayed by [[Bonnie Bartlett]]), and father, David (portrayed by [[John Cullum]]). David Greene served in the [[United States Navy]], and thus the family moved frequently and lived all over the country, including [[Jacksonville, Florida]], [[Norfolk, Virginia, USA|Norfolk, Virginia]], [[Corpus Christi, Texas]], [[Washington, D.C.|Washington D.C.]],<ref name="4x14">{{cite episode | title = Family Practice | series = ER | series-link = ER (TV series) | season = 4 | number = 14}}</ref> [[Kings Bay, Georgia]],<ref name="4x07">{{cite episode | title = Fathers and Sons | series = ER | series-link = ER (TV series) | season = 4 | number = 7}}</ref> and [[Hawaii]], where they spent three years, David's longest assignment.<ref name="8x21">{{cite episode | title = On the Beach | series = ER | series-link = ER (TV series) | season = 8 | number = 21}}</ref> Greene had a very strained relationship with his father, and was decidedly closer to his mother. Greene would often act out in an attempt to upset his father and aimed his goals at the opposite of what his father wanted. Mark thought his father's Navy career mattered more to him than his family, only to later learn that David was on track to be an admiral and turned down the chance in order to come home and help Mark deal with a bully. The most memorable time of his childhood was when his family was in Hawaii, a time he would later recreate with his daughter Rachel during the last few weeks of his life.

While still in high school, Greene met and soon after developed a romantic relationship with Jennifer (Jen). Presumably, their relationship lasted the duration of their time in college, and at some point around the time Greene was at medical school, he married Jennifer. His daughter Rachel was born shortly afterward. While in medical school, he met future colleague [[Doug Ross]]. Greene then completed his internship and residency in the Emergency Department of County General Hospital in [[Chicago, Illinois]], and from there he was awarded the position of Chief Resident of the Emergency Department. While there, Greene developed close friendships with Dr. [[Susan Lewis]], an ER resident, and nurse manager, [[Carol Hathaway]], as well as continuing his close friendship with [[Doug Ross]], now a pediatrician. Although Greene enjoys working the ER, his marriage has been strained by the many nights on call, the long hours, and his wife Jen's decision to complete law school.
