What was House's original diagnostic team composed of in House, M.D.?

House's original diagnostic team was composed of Foreman, Chase, and Cameron.

The three doctors are Dr. Eric Foreman, Dr. Robert Chase, and Dr. Allison Cameron. They work under Gregory House at Princeton-Plainsboro Teaching Hospital during the first seasons, investigating cases that other doctors cannot solve.

Their different backgrounds and personalities drive much of the early series. Foreman is a neurologist with a guarded attitude, Chase is an Australian intensivist, and Cameron is an immunologist. The show uses their disagreements with House and with one another to dramatize competing medical explanations.

Later seasons introduced additional fellows, including Remy “Thirteen” Hadley, Chris Taub, and Lawrence Kutner, and the team changed several times. Those later combinations are common sources of confusion. Foreman, Chase, and Cameron specifically identify the original core team seen when the series begins.
