Geoffrey Atherton is a consumer-researcher who works with Dr. Faye Miller.
The company he works for pitched its services to Sterling Cooper Draper Pryce. At a kickoff meeting Dr. Miller, asked senior staffers to complete a very personal questionnaire that asks for family history, at which Don abruptly excused himself from the presentation.
