Alexandra Lennon-Simon

Executive Director

Alex joins Groundwork Somerville after years of work in youth development and urban agriculture. A native city kid born and raised in Brooklyn NY, Alex grew up going to the Brooklyn Botanic Gardens as a child and continued working there as an educator, passionately connecting city youth to the natural world. Also near and dear to Alex’s heart are issues of social and racial justice, graduating from Bard College with a BA in American Studies and Studies in Race & Ethnicity, with a specific focus on racial and class-based inequities. Alex previously worked at Waltham Fields Community Farm as the Education Director, expanding the education programs, and running a mobile market for low-income Waltham families. Alex is overjoyed to join the Groundwork Somerville team! Outside of work, Alex keeps two beehives, enjoys hiking and camping with her two dogs, embroidery, gardening, and live theater.

Emily Reckard-Mota

Food and Farms Manager and Educator

Emily comes to Groundwork Somerville with a diverse background in education and sustainable agriculture. She discovered the world of sustainable agriculture during her gap year, while volunteering on a WWOOF farm in Peru. Originally from North Carolina, she graduated from UNC Chapel Hill with a degree in Environmental Studies and Anthropology. During college, Emily worked at Transplanting Traditions Community Farm, where she supported refugee farmers in growing and selling vegetables from Myanmar. Emily has taught cooking and gardening education to young people at the NC Botanical Gardens, Mundo Verde PCS in Washington, D.C., and most recently at various Boston Public Schools with Green City Growers. Emily loves being barefoot outside and values the ways that growing food deepens her faith and connection to God. She is passionate about fighting against racism in our food system and has learned a lot from Soul Fire Farm and The Food Project. Out of a desire to connect her faith to her work, Emily strives to keep justice and mercy at the center of her farming practices. In her free time, Emily enjoys making nature mandalas, reading, and hiking with friends.

Nakiba Minahan

Food and Farms Intern

I am Sayeda Nakiba Minahan. I am currently a freshman in college. Green Team was my first job when I was a freshman in high school. Since then I have been more aware of the communities around me. I am orginally from Bangladesh and have been living in the US for about 6 years. Because of Green Team I was able to explore some of the best places in the world, such as the Grand Canyon and Yellowstone National Park. In the future I wish to share the knowledge I earned from Groundwork Somerville with younger generations back in Bangladesh.

Leija Helling

Tufts Tisch Scholar

Hey, my name is Leija and I'm a junior at Tufts University studying Biology and Environmental Studies. I am passionate about nurturing curiosity through environmental education and I'm particularly interested in inclusive ways of practicing, teaching, and communicating science. I grew up in Western Massachusetts working on farms, in kitchens, and with kids in and outside of the classroom. For the past year, I worked on a grassroots environmental health campaign fighting to put people's interests over profits (check it out at Some of my favorite things to do besides spying on bugs and going after corporate polluters are reading, playing ultimate frisbee, and spending time with young people. I'm pumped to grow food, push for environmental justice, and make hands-on science education more accessible at Groundwork. See you in the garden!
