Sept. 15 is the day to be generous to local organizations because many of those donations will be matched. Make a donation to participating organizations through DonorBridge from 7 a.m. to 7 p.m. and contributions of $25 or more will be doubled.

Among the AIDS service organizations benefiting are AIDS Arms, AIDS Interfaith Network, AIDS Outreach Center, Bryan’s House, Legacy Counseling Center and Resource Center Dallas. Other community organizations that are participating include the Turtle Creek Chorale.

DonorBridge is run by Communities Foundation of Texas, with the support of The Dallas Foundation and the Center for Nonprofit Management.
