Name Dr. Phil Perlmutter
Occupation Physician
First Appearance Known Unknowns

Dr. Phil Perlmutter is the doctor House impersonates in the Season 6 episode Known Unknowns. He is an unseen character.

In order to hide the fact he's not registered at a medical conference, House gives the name of one of the other doctors who have registered but haven't shown up.

Later, when House realizes Wilson is going to give a speech in favor of doctor-assisted suicide, he drugs Wilson and takes his place to give the same speech, still impersonating Perlmutter.

When Wilson expresses concern that Perlmutter will suffer professionally because of the speech, House reassures him that he learned that Perlmutter was stuck in Toronto, Canada all weekend and has a perfect alibi.
