FILE - In this Dec. 2, 2015, file photo, Kelby Krabbenhoft, president and CEO of Sanford Health, poses for a photo at the Sanford Pentagon in Sioux Falls, S.D. Krabbenhoft, the head of one of the largest regional health systems in the Midwest, was replaced Tuesday, Nov. 24, 2020, less than a week after telling employees that he had recovered from COVID-19 and was not wearing a mask around the office. Sanford Health said in a release that it has “mutually agreed to part ways” with Krabbenhoft, who took over in 1996. (Joe Ahlquist/The Argus Leader via AP, File)
