Board of Directors

Anna Ghosh is the director of marketing and communications for the Business Alliance for Local Living Economies (BALLE). Anna has a B.S. in Public Relations from the University of Florida (Go Gators!) followed by two decades of experience in communications strategy and media relations for some of the most innovative and change-making businesses, non-profits, events and documentary films. She began working in restaurants at age 15 and married her love for food with her passion for words when she served on the communications advisory committee for Slow Food Nation in 2008 and co-founded the 18 Reasons co-produced discussion series Kitchen Table Talks in 2009. Besides joining the 18 Reasons board in 2013, the job she's most proud of is being mom to her 3-year-old daughter.

Aaron Hardisty has been involved in food security and food education in the Bay Area since 2009. He began as a volunteer for Cooking Matters (then called Operation Frontline) then became a member of the Cooking Matters Advisory Committee. He joins 18 Reasons as board member after serving as a founding board member for Three Squares. Aaron is a Mission District resident who walks18th street between Mission and Dolores at least twice a week to shop at Bi-Rite Market, grab dessert at Bi-Rite Creamery or walk with his wife and mini Shar Pei, Elvis.



Calvin has always been at home in the kitchen, gathering inspiration from Julia Child and cooking meals for the family.  With over twenty years of strategic planning, financial analysis, and operations management experience, he has served as a consultant at Booz Allen & Hamilton, director of strategic planning at Macy’s, and general manager at Joie de Vivre Hospitality.  He has a BS and MBA from Stanford University and attended the Cordon Bleu in Paris where he learned that the key to any dish is to monter au beurre! 

Following a career as a chef, Sam Mogannam re-opened Bi-Rite Market in San Francisco’s Mission District in 1998 in the space his family had operated since 1964. Since then he’s opened Bi-Rite Creamery, founded 18 Reasons, and tilled ground on Bi-Rite’s own Sonoma farms. Sam co-authored Bi-Rite Market’s Eat Good Food: A Grocer’s Guide to Shopping, Cooking & Creating Community Through Food (Ten Speed Press, 2011). He volunteers on the Board of Directors for the National Association of the Specialty Food Trade (NASFT), for the Good Food Awards, and the Community Alliance with Family Farmers (CAFF). He’s the proud father of two girls, ages 9 and 13. 

Sarah has worked on food-related projects in the Bay Area since 2008. She launched the Bay Area’s first Market Match, which gives farmers’ market customers who use food stamps extra funds to spend at the market, and a Veggie Rx program that helped diabetes patients increase their produce consumption while measuring positive health outcomes. Previously, she taught yoga and guided bicycle tours in France. In 2011, she founded the nonprofit Three Squares, which merged with 18 Reasons in 2013. She is passionate about cooking, rock climbing, riding her bike, and, yes, her job. She lives in San Francisco. Contact her at
