At which fictional hospital does House lead the Department of Diagnostic Medicine?

House leads the Department of Diagnostic Medicine at Princeton-Plainsboro Teaching Hospital. The fictional hospital serves as the main professional setting for the series and houses the doctors who investigate its rare cases.

Diagnostic Medicine is presented as a specialized department for patients whose illnesses have resisted ordinary testing or treatment. House supervises a small team, assigns competing hypotheses, and pushes members to reinterpret evidence. This structure gives the show a distinctive blend of medical procedure, detective story, and workplace drama.

Princeton-Plainsboro should not be confused with Princeton University’s real medical facilities or with the real hospitals in nearby New Jersey communities. The program used Princeton locations for exterior imagery, which helped make the fictional institution look authentic. Within the story, the hospital also includes departments such as oncology, neurology, and administration, connecting House’s cases to a wider medical organization.
