David has been a social studies teacher, principal, and founding owner of the Grand Canyon College Preparatory Academy in Tempe, AZ. He grew up reading and watching science and historical fiction and is also a big baseball fan. He combined his passions in the Jigsaw series, which focuses on time-traveling teens thrust into major historical events—many of which never made the standard history books. Born in New York, he now lives in AZ with the love of his life, Gwyn. We are both dog people, and enjoy travel and food.
