Sharona's childhood is only mentioned during a session with Dr. Kroger in the season 3 episode "Mr. Monk and the Girl Who Cried Wolf". Her father, Douglas, owned a hardware store and died when she was a child. This left her mother, Cheryl, to raise Sharona and her younger sister, Gail (Amy Sedaris), who is an actress and appears in the episodes "Mr. Monk and the Earthquake", where Sharona and Benjy stay with her after their apartment is damaged by an earthquake, and "Mr. Monk Goes to the Theater", where she is framed for the death of her costar during a theatrical performance.
