Sullivan Jordan, played by Christa Miller, is the ex-wife of Perry Cox and a retired member of the Sacred Heart Board of Directors. Jordan's father, Quinn Sullivan, had occupied a position in the Board of Directors, and she inherited it after his death. She is the sister of Danni Sullivan (an ex girlfriend of J.D) and the deceased Ben Sullivan. After her divorce with Dr. Cox, they continue to maintain a strictly sexual relationship. However, they both continue to have feelings for each other and eventually get back together shortly before the birth of their son, Jack. However, Jordan does not tell Dr. Cox he is the child's father for several episodes because she wants to make sure he wants to be with her, not because he has to be with her. Though Dr. Cox and Jordan had been shown to bicker, Dr. Cox remarks that Jordan refuses to argue with him because she doesn't want Jack to be emotionally scarred. However, she often makes Jack increasingly feminine in order to annoy Dr. Cox. When Jordan and Dr. Cox find out that their divorce papers weren't signed correctly, and that they are still legally married, their relationship becomes strained. Deciding that marriage was ruining their relationship, Dr. Cox and Jordan have a legal divorce. Later, Dr. Cox and Jordan give birth to a daughter, Jennifer Dylan (named by J.D. after his initials). Also in season 8 both Jordan and Perry start to wear their wedding rings again.

Jordan is portrayed to be sarcastic, vindictive, and cold; she blames this on her parents, but later tells Elliot that her parents were supportive and not the cause of her behavior. Despite her occasional cruelty, Jordan does display loyalty towards friends and sometimes attempts to fix her wrong-doings. She eventually forms a tolerance and almost fondness for Elliot, which seems to stem from both of them being able to manipulate their boyfriends and the fact that they are both "nervous pooers." Elliot and her then boyfriend Keith even double-dated with Jordan and Cox a couple of times. However, in later episodes, Jordan has been easily annoyed by Elliot and in "Their Story" did her best to cause tension between her and Keith. However, she does manage to fix it at the end of the episode. In the later seasons of the show Jordan formed a friendship with Carla and Elliot. In the episode "My Finale" she kisses JD on the cheek, having called him a good lover, but then she realises to her horror that she is becoming nice, before insulting Ted to balance it out. During JD's vision of the future her, Dr. Cox, and family spend Christmas with JD and Elliot, and with Turk and Carla
