Family Giving Tree

SLAC is proud to once again partner with the Family Giving Tree for the annual holiday gift drive. This season, we will be joining the Family Giving Tree to provide physical gifts, virtual gifts and cash donations toward their goal of 45,000 gifts.

 

Since 1990, the Family Giving Tree has delivered over 2 million holiday gifts to children, adults and seniors in need.

 

This winter you can fulfill a holiday wish in two ways:

 

  1. Choose a physical wish card: Select a card featuring the name, age and wish of an individual living in the Bay Area. You can pick up a physical wish card in the lobby area of the 3rd floor of building 137.  Shop for the gift and drop it off with me (Stephanie Carlson) room 309.

 

Gifts must be dropped off no later than Dec. 2.

 

  1. Fund a wish online: Visit the SLAC donation page to select and fund a gift for someone special in the community from the comfort of your home. Family Giving Tree handles all the shopping and packaging, providing a contact-free way to give. This virtual drive is open through Jan. 9, 2026.

 

Visit https://familygivingtree.org/ for more information about Family Giving Tree’s Holiday Wish Drive. 

We are thrilled to embark on this journey together to support our community with kindness, joy, and a wished-for gift. 

Thank you for your support!
