We would like to begin by thanking our editors at Wiley. Mariann Barsolo, thank you for
taking this project on, believing in us, and supporting this book. Special thanks to Toni
Zuccarini Ackley, development editor, for keeping us on track and patiently spending hours
sifting through our docs. And thanks to Sarah Groff-Palermo and Rachel Gunn, our production
editors, for bringing it all together. And thanks to Liz Welch for copyediting.
A huge thank you to Tim Grey for introducing us to everyone at Wiley. Without
Tim’s encouragement, this book might never have been written (or at least never have
been finished). Thanks for all the time spent reviewing our materials and guiding us
through the sometimes perilous process of writing a book. We appreciate your support.
