In this episode of the Healthier Workplaces Show Podcast, we interview industrial hygienist Zack Mansdorf, PhD, CIH, CSP, QEP, FAIHA, as part of our Luminary Series. Zack is a distinguished leader in occupational and environmental health, safety, and sustainability. In 1998, he was recognized as one of the top 10 most influential industrial hygienists. For more than five decades, his career has spanned government service, academia, consulting, and senior corporate leadership, including his tenure as senior vice president of safety, health, and environment at the cosmetics company L’Oréal.  We’re going to talk to Zack about his 50-plus years in OEHS and learn how the field has changed since he started his career.
