Sustainable Management

As an independent family company, we are not bound by short-term “shareholder value,” but to our own values. These are based on sustainability and reliable partnership. Kieback&Peter wants to set a good and pioneering example in the tradition of a down-to-earth medium-size company: We take on responsibility for people, the environment and the economy – internally and externally. The same applies to all our employees. And to a special degree to our executives, who exemplify genuine, sustainable business leadership on the basis of their own convictions. We place a particular importance on meaningful goals and tasks, transparent communication and trusting collaboration.
