For anyone out there who is following the news reports coming out of Haiti and wants to help, I'd like to recommend an organization called Partners in Health. They are the group birthed out of the work of Dr. Paul Farmer, the author of Mountains Beyond Mountains. A while back I read the book and was impressed and really amazed at the work Dr. Farmer was doing and the compassion with which he was doing it. I wrote a review here.
Partners in Health has been on the ground in Haiti for 20 years. Their main base is just close enough to the capitol to be able to offer medical care for the wounded, and just far enough away that it was not badly damaged in the quake. If you're looking for an organization to which you can contribute, this is a good one. Check it out.
