Lonza promotes Stefan Troger to Visp site manager

Lonza has promoted Stefan Troger to site manager of its plant in Visp, Switzerland. He takes up the role next April and will report to Harry Boot. With this appointment, leadership of the site and the Visp Challenge project will be merged into one.

Troger will succeed Stéphane Mischler, who after a long and impressive career spanning more than 30 years, is retiring. He will support Troger and the site management team until his retirement date and will also continue to work with Lonza’s pension fund.

Troger has held several positions within Lonza over the past 19 years. Most recently he was head of Biopharma Manufacturing in Visp and took over the leadership of the Visp Challenge project, which maps out the future set-up of the Visp site.

‘With Stefan Troger we have the possibility to unify the site leadership of the Visp site and project management of Visp Challenge,’ commented Stefan Borgas, chief executive of Lonza.

‘Our Visp site is confronted with major challenges in regards to currency, markets and technologies. The Visp Challenge project is working on two ends: increase productivity (lower cost and higher output from existing plants) in the short- and mid-term and improve the product portfolio to secure the future of Visp in the long-term.

‘Stefan Troger and his team have the right skill sets and the necessary level of positive energy to make this happen.’
