Who's Where: John Puskar and Liz Wetzel appointed to new roles at GM Design

As part of an ongoing strategy at General Motors, this past month has seen a series of moves taking place within the company's design organization in Europe and the US. Two of the key changes have been the appointment of John Puskar to the role of Director of Cross-Brand Strategy, C&T and Components in North America, and that of Liz Wetzel, who has been named Director of GME Design Interior – effectively filling Puskar's role. Puskar, who until recently headed the Opel/Vauxhall Interior Design at the European Design Center in Russelsheim, Germany, majored in Industrial Design at the Cleveland Institute of Art and worked at Ford in both the USA and Germany before joining General Motors as a creative designer at the GMC Brand Center in 1999.
