Oliver Kraxner, financial general manager at Rhode, is going to be the new managing director of the company. He will take over the post of Dr. Stephan Harmening, former chief executive, who quit the company on Feb. 11. Rhode has had quite a few employee changes in the past couple of months. Lewin Berner, CEO of the investment company Square Four, in cooperation with Morgan Stanley, helped the company get out of its bankruptcy in 2008. He claims that the company needed a new leadership figure.
