Alana Jajko - 2018-2019 Communications & Outreach Assistant
Alana recently joined the Susquehanna Greenway Partnership as the 2018-2019 AmeriCorps Communications and Outreach Assistant. A graduate of Bucknell University in Lewisburg, PA, she received a B.A. in Studio Art and Creative Writing with a Classics minor, as well as an M.A. in English with a focus in Environmental Studies. Before joining SGP Alana worked as an editorial assistant for the Bucknell University Press and served as a project manager for a PBS documentary series entitled “Stories of the Susquehanna Valley.” The most recent film in the series, The Coopers and Conservation at the Headwaters of the Susquehanna, allowed her to make connections from one river town to another, sparking a desire to become more involved in communities along the shared waterway. She hopes that SGP will help her do just that! From volunteer work in Nepal to archaeology in Greece and her more recent training as a Pennsylvania Master Naturalist, a common factor in Alana’s ventures has been an interest in natural and cultural landscapes. She looks forward to seeing how the greenway will continue to feed these interests, and how her own experiences will serve the continued growth and development of SGP.
