Editorial Reviews:

“Trauma and the Avoidant Client is just right. It hits the ground running. The eight chapters are well-written, helpful and relevant and each finishes with a great summary of the main therapeutic points. While obviously strongly embedded in attachment theory and backed up with Professor Rob Muller’s research, it is not a tedious theoretical read, and is written by someone with a good deal of clinical skill and knowledge. This is a book for therapists. . . . A very good buy.”
– New Zealand College of Clinical Psychology Journal

“This text is invaluable to a range of healthcare practitioners seeking to understand more deeply how people respond when faced with the challenging prospect of focusing on their vulnerabilities and I would consider this high-recommended reading for those training to become counsellors and psychotherapists.”
-Healthcare Counselling and Psychotherapy Journal (UK)

“[A] practical, useful and empirically based guide….[I]nsightful and relevant to all age groups….[E]asy to read and I would definitely recommend it….[H]ighly practical and insightful.”
– Aotearoa New Zealand Social Work

“Clinical experience blends with research and theory to provide a fine survey of defensive patterns and how they can be changed.”
– Midwest Book Review

“Clinically perceptive, theoretically clear, and research-informed, this book is filled with clinical gems.”
– Leslie S. Greenberg, PhD, Distinguished Research Professor, York University
