From family business to international company

From a small, family-run mechanical workshop in Graenichen, Switzerland, Zehnder has grown into a leading international corporation. The company's roots are deeply intertwined with the entrepreneurial spirit of the Zehnder family. These are visible in Zehnder's corporate culture, customer focus, respect, trust, curiosity, and openness.
