Hands-on care trips to countries in South Africa

Hello, my name is Funda Polat; I'm 23 and in school. I live in Asheville, NC and have been looking for a group of people to go to the poverty stricken countries/regions of South Africa. I currently work in the Emergency Department at one of the big trauma centers in our area and have been dying to help the children that are in need. I just started my research and came across this email address, so I thought I would give it a try. I know I can't do much on my own, but my goal is to find a group or team that makes trips to the countries in South Africa and those like it to do hands-on care. I want to make a difference in a child/adult's life..feed them, bathe them, help them advance in education and healthcare. Any information or help in pursuing this personal dream would be greatly appreciated!!
