Zoey Barkow (born November 19, 1986) joined All Saints as an earnest and eager student nurse from Queens Community College. Zoey is introduced early in Season One, where she shadows long-time super-nurse Jackie Peyton, whom Zoey idolizes. Under Jackie's tutelage, Zoey quickly develops her nursing skills and comes into her own as a nurse. Zoey is eventually promoted to Head of Nursing in the ER and pursues a Master's degree with a goal of becoming a Nurse Practitioner.
Zoey eventually starts dating an EMT named Lenny. After her proposed she lost the ring, which was found by Dr. Cooper. When he placed the ring back on her finger she realized it didn't feel right when Lenny did it and broke off their engagement. Later in the series, she developed a relationship with Dr. Ike Prentiss. Zoey develops friendship with Grace Peyton to help Grace of jealously from Jackie because she believes it's always about "her" as in Jackie.
Zoey Barkow is a child-like nurse that is playful and hilarious and wears ridiculous nurse attire to presume to be a fun nurse. She is good friends with Jackie, because in the beginning she trains Zoey and she wants to be just like Jackie because of her skills of being a nurse.
