Clear objectives and a persistent yet subtle path of execution have led to a result well ahead of the original objectives. Besides being a first class general manager, John has also been an extremely trustworthy, reliable and highly esteemed colleague, and a fine gentleman with a good sense of humor." and "I have been working with John since early 2019 when he joined BU Pigments as the global BU Head. At this point of time the BU faced quite some challenges and the business called for a turnaround. In addition the BU was earmarked for divestment and had to be put on its own feet. Under John’s leadership we developed and implemented a new operating model, created a stand-alone organization and set-up a major transformation program. John spearheaded the entire transformation and managed the numerous internal as well as external stakeholders outstandingly well. He did not shy away from difficult and bold decisions and in the same time managed everything in a socially responsible way. John challenged the organization quite a lot and pushed hard for the necessary actions. All decisions however were solely taken based on proven facts & figures. The new operating model and the transformation program have been successfully followed through and the business on this healthy basis came very well through the Corona crisis. Likewise, the divestment was successfully completed by the end of 2021. John is an inspiring leader with a very broad experience. I have learned a lot from him during the last years and enjoyed working with him."
