Dr. Carolyn Spiro is a doctor of psychiatry, meaning she is qualified to medicate her patients and has a deep understanding of the complicated pharmaceutical market and its relation to mental health. The doctor is personally invested in the health of her patients not only because of her profession, but because her own sister's unstable mental history has provoked her study of psychiatry and motivated her to help others with similar conditions as much as possible. She has written a book about her and her sister's life struggling to understand Schizophrenia. The book is called, Divided Minds: Twin Sisters and Their Journey Through Schizophrenia.
