The holidays are a popular time of year to give back to local nonprofits through donations and volunteering, but there are many opportunities to help year-round in Silicon Valley. Whether you have a couple of hours or a few days a week to spare, Peninsula organizations could use your help with everything from delivering food and maintaining trails to caring for animals and talking to seniors in need of connection. Here are ways to make a difference in the community in December and beyond.

Avenidas: Volunteer from your home through the nonprofit’s Friendly Voices program, which pairs volunteers with older adults through free, weekly phone conversations one to two hours a week. 

In-person opportunities include Avenidas Door to Door, in which volunteers give rides to seniors; helping staff at the Avenidas Rose Kleiner Center with scheduled activities and socializing; facilitating activities and teaching classes; and helping seniors with odd jobs and errands as part of Avenidas Village, the aging-at-home membership program.
