For federal or military employees, a Combined Federal Campaign can make a big impact. Between September 1 and December 15 every year, more than 200 CFC campaigns support health and human service nonprofits with millions of dollars in donations. Outside of the campaign window, you can always support ACS through a donation.
Combined Federal Campaigns are not currently active. Check back on September 1 when the campaign restarts. You can also donate directly to American Cancer Society below.
