• The technical reviewers—Wendy Castleman, David Dick, Kaaren Hanson, Arnie Lund, and Dave Rogers—for taking the time and offering advice and constructive feedback. Their insightful suggestions have improved this book several-fold. Any errors or shortcomings, however, are my own and likely caused by not heeding their advice.

• Len Beasley, for assisting with research and helping with endless rounds of editing drafts of the book's chapters.

• The team at Elsevier: Mary James, my editor, for being patient as I experienced the first-time author struggles and for helping me stay focused and on (revised) schedule; Denise Penrose and Diane Cerra, for giving me the opportunity to write a book on a topic I am so passionate about; and the production team, including copyeditor Jodie Allen and proofreader Deborah Prato, for their talents in clarifying content and designing and laying out the book.

• Clients, colleagues, and friends, who continue to teach, guide, listen, and encourage.

• Sona, my dear wife, for her support and putting up with me during my extended work during the writing and review schedule and for not letting me give up when the going got tough.

• And, Sumi, my little princess, for understanding that daddy needed time by himself to finish the book and for offering to write it so that he had time to play with her.
