Davin Alves of Marion, an 11-year-old, Sippican Elementary School student, set a high bar for himself last year in raising over $900 for food donations he made to the United Way of New Bedford. This year, Davin wanted to do more. He held raffles, raising $3,470 in donations that he used to buy and donate food, adding two more outlets, the Marion Food Bank at the Cushman Community Center and Damien’s Food Pantry in neighboring Wareham.
