Well advised.


The .bieker AG also has a controlling body at its disposal – the advisory board. This consists of six persons from various professional backgrounds. As well as their supervisory responsibility, these executives are important impulse generators for the strategic orientation and the further development of the company. With their many years of experience and their valuable, practical knowledge, the members of the advisory board contribute to the success of the .bieker enterprise.
