Volunteer NH and Granite United Way have partnered to bring you Get Connected, an online hub for volunteerism in New Hampshire. Volunteers use Get Connected to find nearby opportunities that fit their interests and schedules. Nonprofits use it to attract, manage and report on volunteer activities in their organizations. Needs are searchable and categorized by location, organization and/or focus (such as animals, disaster relief, etc.).
