  • Selena Ligrano

    Selena received her BS in Wildlife Ecology and Minor in Horticulture from Washington State University strengthening her connection to plants and the environment. After landscaping in the PNW for over a decade, her passion to work within the local food system sparked a new interest leading her to volunteer at Seattle Tilth within the Food Hub program.

  • Gavin Tiemeyer

    Gavin Tiemeyer is a recent graduate from the Master of Environmental Studies program at the Evergreen State College, where he studied issues related to environmental justice and climate change in the Puget Sound area.

    Prior to joining the team, he cut his teeth gardening professionally during the pandemic in Seattle, where he built a repertoire of horticultural knowledge, pruning skills, and a newfound appreciation for rain gear.

    Forever a proponent of lifelong environmental education, Gavin is happy to teach new gardeners about anything from hydrangea pruning, insect identification, to soil health. “Seattle has a wealth of natural wonders just waiting to be unlocked by the curious mind. I love encouraging others to see nature not as something that exists far away in the perceived wilderness, but directly within the heart of the city where most of us live.”

    When he’s not trying to decipher soil test results, he enjoys playing cacophonous music with friends and drinking morning coffee with cats.
