The Warren Farmers Market began in 2013 as a monthly outdoor market in Courthouse Square in Warren, Ohio. In 2014, the market began operating weekly from June through October. What started as a partnership between Trumbull Neighborhood Partnership (TNP), Lake-to-River Cooperative, Mercy Health, and Trumbull County Combined Health District’s Creating Healthy Communities, then transitioned to being fully funded by TNP’s Garden Resources of Warren (GROW) program under the Trumbull Memorial Health Foundation (TMHF) grant.
