There were many people who helped me build the new CCNA books in 2019 and 2020. First, Kenyon Brown helped me put together the direction for the books and managed the internal editing at Wiley, so thank you, Ken, for working diligently for many months keeping these books moving along. Thanks also to Christine O'Connor, my production editor at Wiley for well over a decade now, as well as Judy Flynn my go-to editor who always does an excellent job! Thanks also to Kim Wimpsett for proofreading and to Todd Montgomery for technical proofreading.

The co-author I used in this book was Donald Robb out of Canada. He helped me put together the two wireless chapters and completely wrote the three DevNet chapters (2123). His knowledge of the subject is second to none and he blew me away! You'll love his work too. You can reach Donald through his popular blog at https://the-packet-thrower.com. He also is a top moderator and contributor at reddit: https://www.reddit.com/r/ccna/.

The top editors I used in the CCNA series included Troy McMillon, who read each chapter in the full series multiple times, making amazing discoveries both technically and editorially. Todd Montgomery was the most excellent tech editor for the complete two book CCNA Series. Also, Monica Lammle read and reread each chapter and really helped me keep the voicing in place throughout the editorial process, which isn't an easy thing to do!
