One year of communicating values

In January 2024, as "The New Boss", I explained in a video statement what is important to us and to me at G+P. After almost a year as the new CEO, it's time for a little look back. Our values take centre stage. Values are a key success factor, especially for SMEs like us.

«With the CPX measurement system, we are on the road all over Switzerland measuring the acoustic effect of road surfaces. During these measurements, I discovered many beautiful places throughout Switzerland and was inspired by the different landscapes: sunsets in the canton of Fribourg, summer days on Lake Maggiore or winding drives up unknown mountain passes. The perfect balance to the daily office routine.»
