Joan Harris is the Office Manager at the Sterling Cooper Draper Pryce advertising agency. Joan held a similar position at the original Sterling Cooper, where for a brief period she also worked as a script reader with Harry Crane in the TV Department. Clients lauded Joan's contributions, but a new male employee was hired when a full-time position opened up.
Though Joan had a lengthy romance with Roger Sterling, she is now married to Dr. Greg Harris, a surgical resident. In anticipation of Greg's appointment as his hospital's Chief Resident, she resigns from Sterling Cooper. When Greg fails to get the position, Joan briefly works at a department store before Roger taps her to help with logistics at Sterling Cooper Draper Pryce. Greg, meanwhile, has announced that he is joining the Army so that he can continue his surgical training. Greg isn't keen on having his wife work, which, he maintains, won't be necessary on a Captain's salary.
