Around a dozen non-profit organizations gathered at Peace Tree Brewing Company yesterday evening for a non-profit volunteer night. The public was invited to come to Peace Tree to meet representatives with the organizations and find out more about what they do. Knoxville Chamber of Commerce Director Larissa Van Donselaar says that she was pleased with the turnout, which she says was constant and steady. People were also enticed with a free pint from Peace Tree after they had visited with members of each organization.
