Trust and Partnership
Trust and long-term business relations are our utmost concerns. This focus on reliability is also reflected in the compositions of the Executive and Advisory Boards. Their passion for technical systems, in particular those that become especially exciting by the software involved, united Heinz Grötzinger, Dr. Udo Konzack and Hans-Peter Zimmermann in 1994. The challenge of founding and developing a systems house and IT service company offered an equally exciting personal and career perspective to all three of them. In early 2016, the founders of Konzept Informationssysteme GmbH placed the operative management of the company into younger hands after several years of preparation. The three former authorized officers Dr. Peer Griebel, Frank Häßler and Dr. Christophe Schoenenberger are the new executive officers. The founding trio forms the new Advisory Board. Both boards work together to promote the further development of the medium-sized enterprise. Since January 2019, following the departure of Dr. Christophe Schoenenberger from the company, the management constists of Dr. Peer Griebel and Frank Häßler.
