Katharina Röhrig grew up at and with GFOS. In 2014, she decided to join the family business, a tech company founded by her father Burkhard Röhrig in 1988. After studying abroad at the University of San Diego, the International College of Management Sydney, and completing her MBA, she was initially a member of the executive board of GFOS mbH.

In 2022, she took over the company together with Dr. Ignace Van Meenen and has since been the chief executive officer of the GFOS GROUP. Katharina Röhrig is known as a thought leader in the field of New Work and represents female leadership in an industry that still tends to be dominated by men, thus breaking through common clichés. She was voted executive board member of the BDI Digital Committee in 2022.

Hence, Dr. Ignace Van Meenen has built a worldwide network as well as extensive experience in the management of national and international companies – from medium-sized enterprises to large corporations. He has been leading the GFOS GROUP as the chief executive officer together with his wife since 2022.
