Alana Jajko
Director of Communications & Outreach
Alana joined the Susquehanna Greenway Partnership in 2018 and was promoted to Director of Communications & Outreach in 2019. Her work is focused on promoting trails and communities within our vibrant and connected Susquehanna Greenway, so that communities in our region can enjoy opportunities to engage with the outdoors. A graduate of Bucknell University in Lewisburg, PA, Alana received a B.A. and M.A. before joining SGP. One of Alana’s earlier endeavors was as project manager for a PBS documentary series entitled “Stories of the Susquehanna Valley.” The narratives of this series allowed her to make connections from one river town to another, sparking a desire to become more involved in communities along the shared waterway. SGP has become an avenue for her to do just that.
In her spare time, Alana enjoys hiking, kayaking, painting, reading, collecting tea, and traveling. During her travels, both in the U.S. and abroad, she’s always on the lookout for ways to get outside and bask in the natural surroundings. Her time at SGP has shown her that these things also exist right in our own backyard in the beautiful Susquehanna Valley. She loves how the Greenway can feed these interests, and how her own experiences can serve the continued growth and development of SGP.
