The successful development of the Group of Companies Nottenkämper is also the result of many years of mutually trusting cooperation with competent regional partners. Our memberships in various associations and federations ensure that the responsible persons of our companies regularly look „beyond the end of their noses“, adress new ideas and in addition to the specific interests of the industry they assume responsibility for society as a whole.
