Reliability and sustainability since 1860

Internationally active and rooted locally: For more than 150 years, WEHRLE has proven its reliable and sustainable service performance for regional and international clients, finding innovative solutions and creating a trustful cooperation with our clients, suppliers and partners.

The most important success factor of our company is the reliable and quality oriented work of our employees. The bond of our employees with their WEHRLE-WERK is unique. Many work in the company already for generations. The ownership of the 5th and 6th generation of the founder's family is a sign and also a source of our entrepreneurial solidity.

Our locally and historically anchored relationship to the city of Emmendingen in the south-west of Germany shapes our close link to the people living and working in this region. In practice, this relation becomes alive in our social commitment, especially in our WEHRLE-WERK Foundation for Nursing Support.
