"The much-anticipated new edition of Dr. Sperry's Handbook of the Diagnosis and Treatment of DSM-5-TR Personality Disorders is a critically needed volume for any mental health clinician working with personality disordered clients. It is evidence based, completely updated, and remarkably practical. This is one of those rare books that should be on the shelf of all mental health professionals and trainees. Dr. Sperry has offered the profession an important and much needed update to a now classic text." Thomas G. Plante , PhD, ABPP, is Professor at Santa Clara University and Emeritus Adjunct Professor in Psychiatry at Stanford University School of Medicine "Uniquely trained as a psychologist and a psychiatrist with extensive clinical experience, Len Sperry MD, PhD is one of the top academic masters in the world in the diagnosis and treatment of personality disorders.

That expertise along with his lifelong career as an educator, Len has the ability to frame cases and theory into a crystal-clear narrative for the reader in his latest edition making it a must read for all MH clinicians." Jon A. Lehrmann , MD, Chair and Charles E. Kubly Professor, Department of Psychiatry and Behavioral Medicine, Medical College of Wisconsin "Sperry's 4th edition of the Handbook of the Diagnosis and Treatment of DSM-5-TR Personality Disorders effectively engages the latest theory and research in this vital and complex area of clinical practice. I consider this the essential volume on the topic because of Sperry's evidence-based insights about the full set of personality disorders integrated with a diverse range of practical treatment strategies. His case conceptualizations weave together the multi-faceted strengths of this approach and offer an excellent set of training tools. This is the key book on personality disorders to own." Steven J.
