Lisa Cuddy is the hospital administrator and House's boss for much of House M.D.
Cuddy serves as Dean of Medicine and hospital administrator at Princeton-Plainsboro Teaching Hospital. She supervises House, manages the institution's finances and staff, and frequently confronts him about rule-breaking, patient safety, and his unconventional methods.
Lisa Edelstein played Cuddy from the first season through the seventh season. The character is both House's professional superior and a major personal presence in his life, creating an ongoing tension between institutional responsibility and loyalty to House's diagnostic abilities.
Allison Cameron and Martha Masters are doctors on House's teams, while Stacy Warner is House's former partner and attorney. None of them holds Cuddy's long-running administrative role.
