Hartwig Siemerling
Hartwig Siemerling, former chief operating officer of Witex USA, has accepted the roles of president, CEO and board member of the company. Siemerling has been leading the operations of Witex since its doors opened in the United States in 1994.

One of Siemerling's first decisions as president and CEO was to welcome Matt Thornton back to Witex as vice president of sales. With the creation of the vice president of sales role, the position of national sales manager was eliminated. As a result, Don McMahon, former national sales manager, has assumed a new role with Witex as the manager of new business development.
