“Exceptionally well written and thoroughly researched, this book is an ideal desktop companion for any busy CBT clinician. Steffen's vast experience shines through on every page; the case examples highlight her warmth and humanity as an exceptional, caring therapist. I appreciate that the book covers clients in midlife—a much-neglected developmental stage—as well as old age. The final chapter, on aging as a therapist, affords rare insight into how competence, knowledge, and humility develop in helping professionals.”
