Perma-Fix Environmental Services late last week appointed Larry Shelton chairman of the board of directors, replacing current Chair Lou Centofanti, the company announced. Centofanti will still remain on the board, as well as continue his other responsibilities as President and CEO of Perma-Fix. The company said the move was “good corporate governance” by adding an additional voice in the leadership ranks. “Larry has been a valuable resource to Perma-Fix since joining the board in 2006,” Centofanti said in a statement. “His knowledge base on the environmental side of the business and his financial expertise make him ideally suited to take on the role of Chairman of the Board. Given the turnaround in our core business as well as the traction we are gaining within our medical isotope business, separating the roles of CEO and Chairman will provide us additional resources to evaluate and pursue various growth opportunities. At the same time, given his role as an independent board member, separation of the roles of Chairman and CEO further reinforces our commitment to good corporate governance.”
