Sustainability is a frustratingly ambiguous term. 

We're here to define it.


Topic by topic, SustainabilityDefined introduces listeners to the fundamentals of sustainability. We break down the landscape, simplify the big ideas, and explore them in greater detail with experts in the field. Despite our most concerted efforts, bad jokes consistently make appearances on the show.


Jay Siegel (the deeper voice that some confuse with Jim Rome's)

Jay has been aware of his inner tree-hugger since his days growing up in Colorado. He likes live music and the feeling of importance he gets when hearing his own voice through a podcast.

Jay received his B.A. from the University of Michigan (Go Blue!) and his Master's of Urban Planning from Cornell University.

Scott Breen (the silkier voice that washes all your worries away)

Scott is often described as a "funny Spock" with his combination of logic and jokes.  He enjoys college hoops and bike riding everywhere. In fact, his favorite part of the day is when both he and the school crossing guard are dancing and saying good morning as he passes by on his ride to work.

Scott received his B.A. from Georgetown University and his J.D./M.P.A. from Indiana University.

Hannah Perry (the muscle behind our research and logistics)

Hannah describes herself as a defender of the little guy. Her talents include naming the species of every tree in the DMV area, listing fun facts about bees, wearing flannel in all weathers, and finding dogs to pet everywhere she goes. Rest assured, moms love Hannah, and not just because she eats so many veggies. One day, she looks forward to having a dog named Broccoli. 

Hannah will receive her B.A. from George Washington University in the Spring of 2017.

Max Sall (failed joke writer / research and logistics)

Max is studying Environmental Studies and Chemistry. He hopes to one day go to medical school, or maybe become a climate scientist, or maybe even become an environmental lawyer. One thing is for certain though: Max will become an amateur beekeeper. You can spot Max by the Wilco patch on his backpack, the Wilco sticker on his laptop, or maybe the Wilco sticker on his reusable water bottle. Max loves podcasts, especially WTF with Marc Maron and SustainabilityDefined.

Max will receive his B.A. from George Washington University in the Spring of 2019.
