Annie Gilmore, Urban Farmer

bio-pic-annieAnnie’s first experience in agriculture came from working on her college’s farm. Though briefly distracted with a stint counting shorebirds for the government, Annie was drawn back into the world of growing veggies with an internship for Green City Growers in 2012. After her first round with GCG, Annie dove into production agriculture on a non-profit farm/wildlife sanctuary, where over the course of three seasons she solidified her love of growing food and working outdoors. Now, four years after her first time with GCG, Annie is back to build upon that knowledge in an urban setting. When not playing/foraging/working outside, you can find Annie eating. Basically all of the time.

Katie O’Connell, Urban Farmer

Katie is senior at Northeastern University about to graduate with a degree in Environmental Studies and Elementary Education. She is interning at Green City Growers for the spring of 2017 as a part of Northeastern’s cooperative (experiential learning) program. Katie hopes to combine her studies in the Environment and Elementary Education to make hands-on outdoor environmental learning a staple for all students, especially those in urban areas with less accessibility to nature. When Katie is not learning from all the experiences to be had at GCG you can find her on the Charles River rowing from when the sunrises until it sets. She is otherwise sleeping or eating.
