Volunteer opportunities include a variety of options for people across ages, abilities, and interests as Seattle’s Mayor Bruce Harrell announced registration has opened for the second One Seattle Day of Service. Volunteer registration is now open for 110 service events in neighborhoods across the City of Seattle. Most volunteer shifts are 2-3 hours, ranging from just a few volunteers to up to 100 per shift. Nearly half of activity opportunities are open to all ages, and more than one third are open to all abilities.
