For several decades the National Coalition to Abolish the Death Penalty (NCADP, www.ncadp.org ) has been doing very good work, including working with state-level organizations working to abolish the death penalty. They recently moved to new office space shared with other organizations at “WeWorks,” so they have a new mailing address and a new address for receiving donation checks.
Mail correspondence to:
NCADP c/o WeWorks
80 M Street S.E.
Washington, DC 20003.
Mail donation checks to a different new address:
P.O. Box 829846
Philadelphia, PA 19182-9846.
Other great organizations include the ACLU (at nationwide and state levels), the Death Penalty Information Center, Equal Justice USA, and other entities. These and other organizations are on the list (unfortunately still using NCADP’s previous address) at this link:
