Jeff Supak, Community Resiliency Program Associate
Jeff Supak began his career with Global Green as an Americorp VISTA in 2011. When he first started at Global Green, Jeff worked with wetland owners in south Louisiana to explore blue carbon as a financing tool for coastal restoration. Now Jeff manages Water Wise NOLA, which represents a group of water professionals and concerned citizens who actively work to address urban water issues in neighborhoods that need it the most.
Jeff grew up in South Texas where his grandparents and parents farm rice. Unfortunately, this type of work is diminishing in Texas due to water issues; thus, Jeff and his family have had many first hand experiences with climate change. It was Hurricane Katrina and its lasting effects that brought Jeff to New Orleans. Once he saw the devastation and the severe inequity that showed itself after Katrina, it inspired Jeff to work with people in the community to provide information sharing and other resources to create positive growth.
Jeff truly loves living in New Orleans! He is one of the very few people who actually enjoy the hot and humid summer because it reminds him of home. His second favorite season is Mardi Gras of course (Mardi Gras isn't just celebrated on Fat Tuesday--it is two months of celebration)! Before and / or after work, you can find Jeff either teaching or practicing yoga at Free to Be Power Yoga studio. He loves yoga because what happens on his mat is relatable to things that happens off his mat. Yoga continually reminds him that anything is truly possible both inside and outside of a yoga studio.
