An OTBKB wrote in to say:
I’m interested in getting involved in a volunteer
organization based in Park Slope or the nearby neighborhoods. I particularly
like groups dealing with: women, kids, the arts, animals. Do you have a good
resource for Brooklyn-based volunteer opportunities?
If readers have ideas please let me know. I will compile them and post on OTBKB. Send as a comment or to louise_crawford(at)yahoo(dot)com.
It isn’t Brooklyn/Park Slope specific, but you can always restrict by zip code @ VolunteerMatch: http://www.volunteermatch.org. Choose Advanced Search, type in your zip code, restrict to 5 miles from location, then sort your results by zip code.
