"Mixed Nuts" is a memoir of a life working in psychotherapy.

Speaking to the layperson and the practitioner alike, even Rick's irreverent humor can’t hide his wisdom, his deep understanding of mental illness, his desire to help heal it quickly and effectively, and his pragmatic and often creative approach to treatment.

Rick considers this the most difficult book he has ever written. It had to be neither a joke book nor a boring psychology textbook. His goal was to give readers an understanding of mental health in a way that was entertaining enough to make them want to turn the page. Reviews suggest that he succeeded.
