Sandy is James Wilson's assistant. She appears briefly in two episodes, and in the Nurse Jeffrey episodes. She is portrayed by actress Christina Vidal. Sandy helps keep Wilson up to date on his appointments and the status of his patients. In Wilson, she is seen telling Wilson that one of his patients wants to see him. In Private Lives, Robert Chase decides to test the theory that people will do things for him because he's good looking. He asks Sandy if he can borrow her car even though he barely knows her. She readily agrees.
