Robin Wittenstein, 48, currently the hospital's chief operating officer, has been tapped to become president and CEO UMDNJ-University Hospital in Newark, NJ. Moody's Investors Services in March warned UMDNJ that its credit rating could be cut, in large part due to operating losses and anticipated state aid cuts to University Hospital. The Moody's report cited a $32 million operating loss for the first six months of the budget year, and "a quick turnaround at the hospital is unlikely," the report said.
