A board-certified pediatrician with the American Academy of Pediatrics, Dr. Louis Borgenicht runs his own practice in Salt Lake City. He is also Assistant Professor of Pediatrics at The University of Utah School of Medicine, and he serves on the Board of Directors for Physicians for Social Responsibility. Dr. Borgenicht lives with his wife, Jody, who has finally learned how to sleep through the night while her husband goes out on calls.

Joe Borgenicht is a D.A.D. who frequently telephones his father for advice. He is also a writer, entrepreneur, and the co-author of The Action Hero's Handbook, The Action Heroine's Handbook, and Undercover Golf. He lives in Salt Lake City with his wife, Melanie, and their sons, Jonah and Eli (who still operate at peak efficiency).

Paul Kepple and Jude Buffum are better known as the Philadelphia-based studio Headcase Design, whose work has been featured in many design publications, such as American Illustration, Communication Arts, and Print. When Jude was an infant, his owners would often program him for extended periods of sleep mode. Paul's owners, on the other hand, tried numerous times to return their model, believing his inability to grow hair was a manufacturer's defect.
