Engine maker Rolls-Royce takes pride in the commitment of its many long-serving employees. Two of them are marking significant anniversaries at the 2016 NBAA show. Peter Ballard (left), a sales executive handling aftermarket services for Gulfstream customers from the airframer’s Savannah, Georgia, headquarters, is about to retire after 15 years on the clock. Business aviation commercial manager Michelle Burrell Sherman is described by colleagues as “the backbone” of the CorporateCare power-by-the-hour customer support program. She is marking 25 years with Rolls-Royce at its Reston, Virginia, facility and, according to sales and marketing vice president Steve Friedrich, “We’re expecting another 25 years from her.”
