Some years ago this charity mailed my wife. I read the mailing and liked what I read about the Addis Ababa Fistula Hospital
(you can also find out more by visiting the link). They do so much more, please visit their site to get the full picture.
This organisation does so much with their donations, operating since 1989 and they have never employed more than a few staff, the office space is donated so donations are spent in the most efficient way possible.
Since receiving the mailing I personally have made donations to Ethiopaid and now this site has made the commitment that all revenue will go to them also.
You can also make a donation directly to them on their site if you wish.
