Since 1995, the family business GERES-Group has been in operation. Founded and led by Norbert & Carmen Wiemann, the company`s philosophy rests on the four bedrocks: efficiency, quality, confidence and strength. It will always be of highest importance to realise high-graded projects with a goal-oriented implementation. We strictly practise lean management to achieve greater flexability and maximum efficiency. In doing so, safeguarding sustainabiliy outranks quantity in our project planning. Consequently, this approach successfully establishes the basis of trust for the internal and external long-term cooperation with the GERES-Group.
