It looks like Alex (Justin Chambers) will be getting a much-needed new mentor on GREY’S ANATOMY.

TV Guide reports that Peter MacNicol has been cast as Dr. Stark, a pediatrics attending who will be working closely with Alex. He will appear in at least two episodes beginning during November sweeps.

While MacNicol is best known for his roles on Numb3rs, 24, and Ally McBeal, this is not his first time on a hospital drama. He played in-house attorney Alan Birch during the first two seasons of David E. Kelley’s 1990s medical series Chicago Hope.

Grey’s Anatomy airs on ABC Thursday nights at 9pm/8 central.
