Rank: 34
Ronald Rittenmeyer
Executive chairman and CEO, Tenet Healthcare Corp.
Rittenmeyer has been executive chairman and CEO at Tenet since 2017 and has served on the health system’s board since 2010. The pandemic has taken Tenet’s earnings on a roller-coaster ride in 2020. Thanks to cost-cutting, the company saw a resurgence in earnings year-over-year for the second quarter ended June 30 even with elective procedures almost completely shut down for much of the period. But a spike in COVID-19 cases proved more challenging in the third quarter.
