If you are looking for a Christian relief organization working in Haiti, let me recommend WFR Relief, located in Louisiana. Led by Don Yelton, WFR has a solid track record for effective compassion in times of disaster, having “provided humanitarian aid and disaster relief in 50 countries since 1981.” They distinguished themselves, for instance, in the wake of Hurricane Katrina.
An article about Yelton and WFR is here. WFR’s donation page is here.
