I WOULD LIKE to thank Deborah Malmud and the folks of W. W. Norton for their guidance, support, and hard work in the creation of this book. Thanks also to my colleagues at Pepperdine University, especially Vanessa Davis for her enthusiastic contribution to this effort. I would like to express my gratitude to my Interpersonal Neurobiology family for their kindness, commitment to healing others, and their support for one another, including Bonnie Badenoch, Bonnie Goldstein, Kyra Haglund, Richard Hill, Pat Ogden, Jaak Panksepp, Debra Pearce-McCall, Allan Schore, Dan Siegel, Marion Solomon, Stan Tatkin, and Bessel van der Kolk. A very special thanks goes to Erin Santos who, with great patience and attention to detail, oversaw all aspects of this book, contributed many valuable ideas, and smiled all the way. And finally, thanks to Susan and Sam for warming my heart at the start of each day.
