Roma Maffia will guest star in a multi-episode arc on Grey's Anatomy this season.

According to TV Guide, Nip/Tuck veteran Maffia will play Roberta, a member of the hospital's board, who will first appear November 29 in the seventh episode of Grey's Anatomy Season 9, "I Was Made for Lovin' You."

Roberta and the board will likely be involved in the plane crash lawsuit fallout.

"We've got the whole lawsuit, which really starts to blow up this [week]," Chandra Wilson says. "Where that's going to take all of the participants, and who's going to ultimately end up with the blame for the accident?"

"I think that's going to also come in as a surprise."

Maffia's notable television credits include Law & Order, Off the Map, Dexter, CSI, The Sopranos, Ally McBeal, Judging Amy, Criminal Minds, Boston Legal, The West Wing and ER.
