Matt Masiero - Masiero grew up in Manchester by the Sea, Massachusetts and graduated from The Wentworth Institute of Technology in Boston in 1977. In 1979, at the age of 21, Matt moved to the Berkshires and joined forces with his brother Chris to open the roadside produce stand that would soon become Guido’s Fresh Marketplace on Route 7 in Pittsfield. A Great Barrington location opened in 1995, with both stores operating on a marketplace model where tenant businesses manage the meat and fish, floral and gift, and kitchenware selection alongside the Guido’s produce, grocery, cafés, and prepared food and deli departments. The stores employ over 300 people, and, as one of the largest employers in the Berkshires, Guido’s has followed a tradition of quality service and community support, especially during the COVID-19 pandemic. Mr. Masiero and his brother plan to retire at the end of 2023 as Guido’s leadership transitions to the next generation of the Masiero family. Mr. Masiero brings with him over four decades of experience in food retail, management, and community giving, as well as a deep commitment to fighting food insecurity in the region.

In addition, the Board would like to cite Mel Greenberg, for his longtime help for those suffering from food insecurity. He also founded Berkshires Bounty, a predecessor to our organization, more than 25 years ago to help remedy the issue. Mel passed away soon after Backyard Bounty merged with Berkshires Bounty during 2019. He is sorely missed by everyone in Berkshire Bounty and everyone who knew him and his good works.
