Rodenstock has recruited top executives of Marine Optical and Sola International to help run its own growing North American operations. David Eichelberger, former vice president of sales at Marine, becomes Rodenstock North America's vice president of sales. David Provow, fomer vice president of manufacturing at Sola, is now vice president of Rodenstock N.A. in charge of technical operations at the latter's new manufacturing facility at Columbus, Ohio. Equipped with Rodenstock's proprietary Automated Prescription Technology, which cuts down on manufacturing costs and inventories in the pipeline, the 120,000-square-foot plant was inaugurated last October.
