Picture of the Headqarter of Henke Sass Wolf and the global presence.

We're here for you
across the Globe.

Eight Locations,
one Quality pledge.

From the heart of the medical technology sector into the whole wide world.

More than 80 percent of our customers are outside of Germany – that is why a global presence is extremely important to us to always maintain customer proximity. Since the company was founded in 1921, we have been based in Tuttlingen, the heart of the world's medical technology sector. This is also where our "doer" mentality comes from, our innovative spirit and our emphasis on quality. And it is exactly this foundation of values that we are duplicating at our international locations in order to be able to produce our select range of top instruments for special medical technology and industrial segments at the high level of HSW quality you are used to.
