Joy Darkhas worked in the healthcare IT field in several capacities. She first worked as a help desk technician providing first-level support at a company that supports more than 130 hospitals in 29 states. Later she focused on providing second-level support for clinical information systems, specializing in perioperative information systems and the emergency department information systems. Next she switched gears to become a support operations specialist, helping to design support protocols and structures as well as managing the transition of support when hospitals converted information systems. Now she has authored the CompTIA Healthcare IT Technician HIT-001 Cert Guideand contributes in writing other technical books. Before healthcare IT, Joy was an elementary school teacher in both the United States and in South America. She lives in Dalton, Georgia, with her sister and Doberman dog. She has two sisters who are physicians (anesthesiology and emergency medicine) who have shared plenty of stories, facts, and opinions about the healthcare environment that have helped to shape the content in this book.
