She is Lou Grant’s daughter and, just like her father, she is a very intelligent lawyer. This is why her father was bold enough to appoint her as the firm’s new CEO when he retired. She runs the firm according to her father’s blueprint and still visits him occasionally to ask for advice and also to keep him abreast of the situation of things. Callie rarely attends to court cases as she is usually too occupied. Instead, she entrusts the court cases to the several lawyers that are recruited by her father.
