Heather Headley has joined the cast of Chicago Med for season 4 in a recurring role.

She guest starred in the season 3 finale as Gwen Garrett, the new chief operating officer of Chicago Med and a Harvard grad hired to “rein in the costs,” causing her to clash with S. Epatha Merkerson’s Sharon Goodwin.

A Tony winner for Elton John and Tim Rice’s Aida, Grammy-winner Headley also recurred in the first season of Netflix’s She’s Gotta Have It. 

Chicago Med, from Law and Order creator Dick Wolf, shares continuity with NBC’s other Chicago shows and follows “the day-to-day chaos of the city’s newest state-of-the-art trauma center and look into the lives of the courageous doctors, nurses and staff who hold it all together.”

Nick Gehlfuss, Torrey DeVitto, Colin Donnell, Norma Kuhling, Oliver Platt, Rachel DiPillo, Brian Tee, S. Epatha Merkerson, Yaya DaCosta and Marlyne Barrett star.
