Dr. Herzog is the psychologist hired by Brian and Brenda to evaluate Molly and to give testimony on their behalf. Dr. Herzog advises that Molly be placed in Brian's custody, and claims that Molly has been traumatized by her excessive exposure to her mother's sexual life. Dr. Herzog is paid $5,000 for his services, a fact which Muth brings to light in the courtroom in an attempt to call Herzog's impartiality into question.
