Norbert Gerling, business unit manager for opththalmic surfacing at Satisloh, based at its German subsidiary in Wetzlar, is leaving the company. His duties are being taken over by Andreas Kunzmann, the Swiss-based chief executive of Satisloh appointed one year ago. Another executive based in Wezlar, Christoph Weber, who was in charge of sales in Europe and countries outside Asia and North America, has also left Satisloh as the company is centralizing sales at its head office in Baar, Switzerland, to increase efficiency. As part of the move, Christian Jakober takes over Weber's role in addition to his current position, where he handles key accounts and oversees sales in Latin America. Jakober, who has been with Satisloh since 1999, will be a member of the executive board.
