Board of Directors

Our all-volunteer Board of Directors includes Owners who are committed to building a thriving community-owned grocery store. They come from diverse backgrounds, from farmers to chemists to engineers and stay-at-home moms and dads. If you’re a passionate Co-op Owner, email to learn how you can join our Board!*

This will be the most momentous year in the history of the Co-op, as our new Directors will help lead us to Opening Day!

Evan Merck


I moved to Maynard in 2020 and am currently the operations manager of Hi-Rise Bread Co. in Cambridge. Previously, I worked in Vermont as a farmhand on a small, regenerative grazing cattle farm and as a farmer/cook at a semester program after time in higher education administration in Boston. I enjoy gardening, playing cards, and dreaming of traveling to vineyards in France. My favorite place to work and live is at the intersection of food systems and the communities that give them life. I’m thrilled about the opportunity to work with the Co-op at such an exciting time!

Debby Andell


I stopped eating meat as a teenager, so I naturally gravitated toward food co-ops to find the alternative products I needed. Having happily shopped in other food co-ops, I am really excited about our store opening this year! I am member #190 and have volunteered where needed, including tabling, the Capital Campaign Committee and the Food Justice Committee. I am running for the board because I recently retired from Mass Audubon, and now have more time to dedicate to the organizations I am passionate about.
As a longtime Acton resident, I am also involved with the Swap Shop in Acton, the Acton Boxborough Farmers Market and Green Acton. The Acton Boxborough Farmers Market is producer-only, which means vendors may sell only the produce and/or value-added products that they themselves grow or make. As a market manager, I enjoy stocking up on Sundays with a wonderful variety of local products.

Mark Lo


Mark Lo lives in West Concord and has been volunteering for Assabet Co-op Market since shortly after he and his wife joined the co-op in 2020. Mark served as a member of the Store Development Committee from 2020-2021 and has been a member of the Outreach Committee ever since. He is strongly committed to supporting local agriculture and has been a member of local CSAs for more than 20 years. He loves food, cooking, and even grocery shopping! Mark’s recent volunteer experience includes five years as a board member for Concord-Carlisle Youth Hockey, for which he also served as Ice Scheduler and Goalie Coordinator. Professionally, he has more than 25 years of experience as a technical writer in the software industry.

Amanda Patel


I live in Maynard and work at Suffolk University as a management professor. I teach organizational behavior and human resource management and do cool (totally unbiased opinion) research on employee health and well-being. My research includes how our workplace eating behaviors affect our coworkers’ perceptions of us! At home, I craft, refinish furniture, and bake with my family. I support the co-op because its mission for a positive impact on well-being at so many levels is an important endeavor. I hope that by running for the board I demonstrate to my children the importance of service to one’s community.

Siobain Mitchell


Siobain has been with the initiative since its beginning. She believes the Co-op will be an integral part of a thriving local economy and will make the area more resilient. Siobain has a B.S. from the University of Massachusetts at Amherst and worked for 10 years in mortgage banking before taking time off to raise her family. Since then she has gone back to school and is now working towards CFP® certification.

Nancy Kerr


We came to West Concord in 1987 when our daughter started kindergarten. I am now retired from working as a Nutritionist (WIC Program) and later at an Employee Assistance Program. My time is free to concentrate on our exciting new co-op!

Besides anticipating the opening of ACM, I have been helping settle newcomers, using my intermediate Spanish to help ease the process. My first ‘adult’ job was as Manager of the Yellow Sun Coop in Amherst. It was my home and my social life. I know what co-ops can do for a community. Good things will happen here! Huge thanks for those who have brought us this far; I’m ready to pitch in.

David Gerratt


An Acton resident for nearly 30 years, David served on the board of a storefront co-op in western Mass. and worked as a communications consultant and graphic designer with national, regional, and local co-op organizations. He has been working with the Acton-Boxborough Farmers Market since its inception in 2009. David owns and operates two home-based businesses. DG Communications works primarily with organizations that promote environmental health and social and economic equality — the Union of Concerned Scientists, Farm Aid, and Oxfam America are among his long-term clients. And Fugitive Productions brings musicians, storytellers, and comedians to local venues.

Laura Mattei


I want to help the Co-op realize our dream of building our store and strengthening our local economy and community. In these extremely stressful times, it feels even more important to strengthen our local connections and communities. I have been a member of the Co-op since the very early stages (Member #20) and I have a long track record of volunteering to support our coop. I volunteered in the first year making phone calls to recruit members, then volunteered over the years at tabling events. In the last three months, I have been active with our Capital Campaign contacting other Owners about the opportunity to invest in our store. I am passionate about healthy food, healthy land management and taking care of our environment and the planet. I have over 25 years of experience working as a program manager with non-profits in the field of land and water conservation. I enjoy cooking, hiking, biking, lake swimming, snow-shoeing and cross-country skiing.

Donna Brown


I am a life-long resident of the area and a wife, mother, and now grandmother. My greatest strengths are my strong community ties and wealth of experience. I earned my MBA while raising two children and working full-time, and I now work in the business office of a private school and serve as assistant director of their summer program. I’ve been a co-op member since 2017 and served on the Capital Campaign Committee, helping to raise more than $2M for our store. I’ve also served as a board member of a housing co-op and I currently serve on the Board of Sunshine Nursery School.
