Sarah Janssen
I grew up in rural northern Illinois and was the first in my family to go to college. My love of learning then led me to get an MD and PhD in Reproductive Biology from the University of Illinois. I moved from the heartland to San Francisco to do my residency training in Occupational and Environmental Medicine and get a Masters in Public Health. Instead of treating one patient at time, I work to protect vulnerable populations from chemical threats to development, reproduction and fertility. Much of my policy work focuses on hormone disrupting chemicals like BPA, phthalates, flame retardants and anti-bacterials. Like any parent, I want to protect my child from harm and I find a lot of inspiration from my daughter. When I’m not at work, you’ll find us at Ocean Beach, at one of the many great parks around the Bay area, or spending a quiet moment at home reading a book.
