I'm sure that we have all been humbled by the suffering in Haiti. If you are still looking for a reliable organization (that has 501(c)(3) status) with which to entrust your donation, then take a look at Partners in Health. If you haven't heard of them...they are a reputable organization that has been working on the ground in Haiti for over 20 years. You can click here to take a look through their website, or here's a link directly to donate with them:
