Joan HollowayPlayed by: Christina Hendricks
Joan Holloway is the head secretary at Sterling Cooper. She's beautiful, and she knows it.
Joan carried on an affair with Roger Sterling for awhile; she also has been intimate with Paul Kinsey from the office. Now, John is married to a man that doesn't seem to respect her at all. He even raped her once.
Holloway has worked at the advertising agency for nine years.
Joan: I don't think you could afford it.
