Head of the Grossberg Criminal Defense law firm, boss and mentor to both Mia Fey and Diego Armando.

Personality: Grossberg is a mild-mannered man and, we have to assume, a skilled attorney. He's usually cheerful and well-meaning but also something of a pessimist. He wants to do the best for his clients, but at the same time isn't about to put himself on the line for their sake.
