San Francisco Firefighters Annual Toy Program

100 First Street is participating in the San Francisco Firefighters Annual Toy Program! We’ll be collecting toys between November 20th and December 12th. The toy collection barrel will be located at the north end of the main lobby elevators (Mission St. side).

The Firefighters have asked us to emphasize that toys be new and unwrapped so they can be sorted for kids by age group. We encourage you to review the list of Toy Donation Suggestions put together by the SFFD for this year’s program.

Thank you for your participation in our Toy Drive and best wishes for a healthy and happy holiday season.
