By MARK EVANS [email protected] Jennifer Mueller is confident she is up to the huge challenge of taking over the Ste. Genevieve County Health Department. Like Chester W Nimitz, who took over command of the U.S. Pacific Fleet after Pearl Harbor, Mueller is taking over the health department at a trying time, in the midst of the COVID-19 pandemic and just as the logistics of distributing vaccines for the caronavirus are being worked out. In addition, since long-time administrator Sandra Bell left in early July, the department has fallen behind in billing and other paperwork critical to maintaining incoming revenue.
