For the third time in less than a year, The Western Pennsylvania Hospital and its Forbes Regional affiliate have a new chief executive officer. Healthcare consultant Dawn Gideon will replace Ed Klaman. Klaman re-emerged from retirement to run Western Pennsylvania Hospital on an interim basis after Mark Palmer resigned. Palmer's exit came just a week after Jerry Fedele, chief executive of parent group West Penn Allegheny Health System, departed amid concerns about the pace of a long-promised consolidation of The Western Pennsylvania Hospital and Allegheny General Hospital.
