Dr. Tina Thomas’s work establishing the biological substrate of the nine Enneagram personality types could prove to be a major breakthrough in our field. While those of us who have worked with the spiritual and psychological implications of this system for many years have never doubted its objectivity and immense usefulness, it will be helpful to have an empirically based explanation of why the Enneagram is so able to capture, with precision and elegance, the personality categories that we see in human beings across cultures and in different ages. While other studies have validated the objectivity of the nine Enneagram personality types, no one before has attempted to ground the origin of personality in brain chemistry the way Dr. Thomas has. This is truly pioneering work which has many profound and practical applications. - Don Richard Riso, bestselling author of "Personality Types" and "The Wisdom of the Enneagram"

In this lively book, Dr. Thomas presents her audacious case for integrating the wide range of research on personality into “OBT” (One Big Theory) that has direct applications to everyday life, and is illustrated with a multitude of vivid and compelling examples. - David C. Funder, Distinguished Professor, Ph.D., Stanford University, 1979, author of The Personality Puzzle

Step aside Dr. Phil; move over Dr. Oz. I truly believe that Dr. Tina Thomas is to personality psychology what Einstein was to physics and what Watson and Crick were to biology. - Eric Schulze MD PhD, researcher, CEO Lifetrack Medical Systems,certified Enneagram teacher

Dr. T has done it again! Her first book, "The Ultimate Edge: How to Be, Do or Get Anything You Want" has innovative dynamic tools for goal achievement and success. And now, "Who Do You Think You Are?" is a revolutionary book that brings personal development to another level!

Dr T has an uncanny ability to combine the art of psychology and the science of biology to create elegant ways to increase self-compassion, improve relationships and help people to become self-actualized. - Richard Tscherne PhD, clinical psychologist, Director of The Gestalt Institute and Relationship Center of New York and author of "The Little Engine That Did It"

Dr. Tina Thomas’ book "Who Do You Think You Are?" is a fascinating exploration of the study of personality and the way self-knowledge can be used by readers to better their interactions with others. Readers will benefit from her intellectual, but conversational, style of writing and her thorough analysis of the subject. There seems to be little in the book that doesn’t have a straightforward usefulness attached to it. - Denis Boyles, author, former university lecturer, contributing and senior editor of Men’s Health, National Lampoon and The New York Times Magazine
