Jennifer Sass

I grew up in the Canadian prairies where I learned to love open spaces, wild places, big skies, long summer nights, cozy cold winters, and the comfort of good friends. I came to the US as a post-doctoral student of toxicology and environmental health. After about a dozen successful years as a bench scientist conducting basic medical research, I wanted to transition into policy work. I joined NRDC in 2001 to work towards strengthening the regulation of toxic chemicals. When not in the office I like to hike, bike, white water kayak, and walk my dog.
