This book is the product of many years, many friendships and collaborations. I am grateful to the best teachers a physician could have—my patients. I wish to acknowledge and thank the staff at the Amen Clinics, especially through our growth over the past twenty-four years. In addition, I wish to thank Jane Massengill and Emmett Miller, who have made significant contributions to this book. I am also thankful to the many professionals who have helped me develop and spread this work, including Earl Henslin, Joseph Annibali, Kristen Willeumier, Larry Momaya, Ari Darmal, Garrett Halweg, Tim Earnest, Brad Johnson, Jennifer Love, Mona Karimpour, Jay Faber, Bob Alpern, Riz Malik, Liz Stuller, Bob Licata, Martin Waugh, Lilly Somner, Manuel Trujillo, Sandi Lowe, Jeff Ditzell, Mittsi Crossman, Ted Henderson, Rob Tarzwell, Phil Cohen, John Thornton, Howard Schneider, Mike Uszler, Dennis Alters, Rick Lavine, Sheila Krystal, Terry McGuire, Dan Pavel, Rob Kohn, Joseph Wu, Karen Lansing, Rick Gilbert, Leon and Linda Webber, Bill Klindt, David Smith, Jack Felton, Mark Kosins, and Jayson Graves.
I also wish to thank Faith Hamlin and the wonderful people at Sanford J. Greenberger Associates who have represented me around the world for more than fifteen years, and my editor at Berkley, Denise Silvestro.
I also wish to thank my children, Antony, Breanne, Kaitlyn, and Chloe who not only give me great stories, but have given me love and affection, and are a continual source of pride. And, of course, my amazing wife, Tana, who has supported and loved me during the revision of this book and the writing of many others.
