Frank and I worked together at WPP from 2003 through 2009. He was initially the German CFO of our media agency MEC and in 2006 was promoted to the position of CFO of GroupM, the parent company of WPP’s media investment management agencies in Germany. Frank’s financial and strategic expertise and business insights made him a strong contributor to our business. Frank was open and forthright with his opinions and focussed on solving problems. Frank and I worked together over a long period of time and I appreciated his professionalism and his open and constructive approach.
