Andersen Corp., the largest maker of windows and doors in North America, is undergoing a rare change of legal department leadership, with chief legal officer Alan Bernick retiring after nearly a quarter-century and passing the reins to his top deputy, general counsel Andrea Nordaune.

Bernick, who joined Andersen in 2000, and Nordaune, who joined in 1998, have helped oversee a period of historic growth at the privately held company, which is majority-owned by the Andersen family. The company, founded in 1903, now has 13,000 employees, $3.4 billion in annual revenue and more than 30 manufacturing facilities, logistics centers and retail locations.
