Based on more than twenty-five years of clinical work with juvenile offenders as well as training parents, teachers, counselors and law enforcement, and supported by research in neuroscience, Changeable presents a radical new way of thinking about challenging and unwanted behavior -- Collaborative Problem Solving -- that builds empathy, helps others reach their full potential, and most of all really works. Changeable gives parents, teachers, CEOs and anyone interested in learning about why we behave the way we do a roadmap for helping people grow.
