As with any book, there are many people we're grateful to for contributing to this project in so many different ways. We'll start with our Deloitte colleagues, present and past.

For transforming a spark of an idea into a reality, creating Business Chemistry from the ground up, thanks to Brian Fugere, Jennifer Juneau, Naomi Bagdonas, and Neda Shemluck. And for being part of the evolving team that has shepherded Business Chemistry through its early years and made it what it is today, thanks to Grace Lee, Danielle Fowle, Kristin Pech, Rebecca Adams Zuteck, Devon O'Malley, Jake Lewitz, Cree Scott, Leigh Otey, Sarah Snow, and Swati Kundu.

For helping get the story of Business Chemistry out of our heads and onto paper/screen by reading chapters, making suggestions, checking our work, and generally keeping us out of trouble, thanks to Sean Kelly, Stephanie Quarls, Nick Murphy, Katie Baird, Jim Guszcza, Kimmerly Cordes, Kristi Loughran, Tony Scoles, and Debbra Stolarik. Thanks in particular to Selena Rezvani, who played an especially central role in the development of this book as resident thought-partner and hand-holder, and to Joanne Ruelos Diaz, who helped wrangle the many minute details that brought it over the finish line. For getting the word out about Business Chemistry and this book, thanks to Shelley McNeill, Grace Pai Leonard, Michelle DeZabala, and John Connors. For making our work look beautiful, thanks to Patricia Mozetic and Randy Yoshio Okamura. Thanks to Punit Renjen for helping to make Business Chemistry a global phenomenon and for writing the foreword. For their constant support and guidance, and championing of Business Chemistry, special thanks to Diana O'Brien and Ken Clinchy.

There are far too many other people at Deloitte (thousands) to thank for bringing Business Chemistry to our colleagues and clients over the years, but we especially want to recognize our global network of certified Business Chemistry facilitators and the entire Deloitte Greenhouse team for sharing the Business Chemistry love far and wide, and bringing back experiences that have enriched our own understanding of working styles and relationships.

Finally, thanks to the team at Wiley, especially Richard Narramore, Danielle Serpica, Vicki Adang, Peter Knox, Christina Verigan, Jocelyn Kwiatkowski, and Pete Gaughan.

From Suzanne: Thanks August and Sinikka for keeping me laughing and allowing me the time to get this book written, even when you would rather have had my attention! At least now you have something to point to when someone asks, “What does your mom do?” For the rest of my family, thanks for your ongoing love and support: Nancy and Mike (that's Mom and Dad), Michelle and Jemma, Shannon, Jim and Toivo, Phon, Sambok, Matthew, Catherine, Michael and Edward, Tim and Ana (whom I particularly appreciate as my work-from-home partner and frequent sounding board). To my many amazing friends who have listened to me talk about this work (and everything else) over so many cups of coffee and glasses of wine—you all know who you are—what would I do without you? And to MJ, thanks for being there to listen, talk, and offer suggestions. (You are a patient and brave man. ) Finally, to Kim, I'm grateful for the space you've given me to focus on what I love to do, and for all you've taught me about how to make my work interesting and compelling (rather than just thorough and accurate).

From Kim: Thanks to Suzanne for being a fantastic co-author and for helping make this book-writing project both productive and enjoyable. Thanks to my mom and dad (John and Gale) for enthusiastically reading everything I've ever written, and providing input and encouragement. Thanks to Oliver and Alex, my amazing sons, who delight me every day and who have been so understanding when I need to work. (They also are a hit at dinner parties, guessing the guests' Business Chemistry types.) And finally thanks to my husband, Jacob, for everything, including being my test Driver helping inspire and improve my work.
