Kathleen Shepherd is the sister of Derek and Amelia Shepherd.


Early LifeEdit

Kathleen was born into a large family in New York. The family often meets up on holidays, although when Derek stopped coming, Kathleen asked Nancy to visit him in order to find out why Meredith's panties were on the bulletin board. ("Let the Angels Commit")

Derek Needing a NerveEdit

Meredith ordered Heather Brooks to call all of Derek's sisters to ask them to donate a nerve. Heather mentioned she left Kathleen a message. Kathleen somehow got Heather's phone number and called her back. It is left unknown why she called because Heather hung up on her, and everyone she was on the phone with, on Meredith's orders. ("Love Turns You Upside Down")

Amelia's New York VisitEdit

When Nancy learned that Amelia was in town, she invited Amelia and Link, thinking he was her husband, Owen, to dinner. She also called Kathleen and Liz, though Liz was unable to attend. At dinner, things were tense, but then blew up when Carolyn arrived and revealed the lie. After they discussed Amelia's history, Link and Amelia left. ("Good Shepherd")



She is married. Her husband is a diplomat.


She has children. Amelia describes her as Martha Stewart if Martha Stewart had the ability to diagnose you with a mental condition. This indicates that the sisters are not very fond of each other.


Kathleen, like the rest of the Shepherd family, is a doctor, trained in psychiatry.
