Claudia is the housemistress of the Hawthorne dormitory at Wexford Sixth Form College. She is short, maybe just five feet tall but broad nonetheless. She has a flushed, deep red face and large hands and her hair is cut in a bobcut that is almost completely square. She has a loud, ringing voice that Rory describes as 'penetrating'.
As the housemistress of Hawthorne, Claudia has an office that is to the left of the doorway - the room is painted a deep shade of maroon and a large Oriental rug covers the floor. As a hockey fanatic, her walls are lined with hockey sticks, pictures of hockey teams and various hockey-related awards.
