What People are Saying About John P. Forsyth

“[John P. Forsyth and Georg H. Eiffert] raise the inevitable truth that anxiety is a part of all of us, and they show us the way, through willingness, compassion, mindfulness, and acceptance of ourselves and others, to live a life worth the living, to understand our important values and to live in concert with them.”
—Richard G. Heimberg, PhD, professor of psychology and director of the Adult Anxiety Clinic of Temple University

“Ably surfing the dual currents of traditional exposure and acceptance based treatments for anxiety, the authors of this resourceful workbook [The Mindfulness and Acceptance Workbook for Anxiety] illustrate the synergies to be found in their combination. This book is a ‘must read’ for anyone encountering anxiety as a barrier to a leading a fuller life.”
—Zindel Segal, PhD, author of The Mindful Way Through Depression

"John P. Forsyth and Georg H. Eifert combine the accumulated wisdom of the ages with up-to-date, cutting-edge developments in scientific psychology. By emphasizing acceptance of toxic emotions (and illustrating ways to accomplish this), rather than struggling to overcome them, the person inside you may finally emerge to set your life on a new, productive, and valued course. Highly recommended for all those struggling with worry, anxiety, and fear."
— David H. Barlow, PhD, professor of psychology and psychiatry at Boston University and author of Anxiety and Its Disorders
