Christen Mayer, 37
Senior director, infection prevention and quality, Tenet Healthcare Corp.
Mayer has been an integral part of Tenet’s response to COVID-19, including helping to standardize infection prevention protocols across the system. Mayer also helped design early iterations of federal data reporting for suspected and confirmed COVID-19 cases. The reporting process was centralized through Tenet’s headquarters, helping reduce the burden on front-line staff. Mayer also cautioned Tenet leaders against using controversial ethylene oxide to clean N95 masks, which was ultimately deemed unsafe.
