Tracy Syrstad is a Microsoft Excel developer and author of nine Excel books. She has been helping people with Microsoft Office issues since 1997, when she discovered free online forums where anyone could ask and answer questions. Tracy found out she enjoyed teaching others new skills, and when she began working as a developer, she was able to integrate the fun of teaching with one-on-one online desktop sharing sessions. Tracy lives on an acreage in eastern South Dakota with her husband, one dog, two cats, one horse, and a variety of wild foxes, squirrels, and rabbits.
