Family Jansen is a family firm with tradition and deep roots in the region. Values such as the sense of responsibility, social commitment, respect and cohesion are as essential to the company today as they were when it was founded. Jansen recognises the invaluable contribution of its employees and therefore pursues a sustainable personnel policy.
