Donna has worked at the parks department longer than Leslie, and is one of the few people who can speak sternly to Ron Swanson. She is the proud owner of a Mercedes, which she is extremely protective of and often brags about. As with Jerry Gergich, the personality for Donna was not established until the second season, but Retta was cast during the first season because the producers liked her, and they decided they would establish her character as the series progressed.
