One of our dear missionaries on the Kenya field is Miss Britt Anderson ( http://www.lcms.org/britt.anderson ), who is currently working with a primary school in Kibera. The Lutheran Hour Ministries program recently featured this school, Karama Academy - Kibera, in a video series they produced as part of the Online Mission Trip programming. See a little bit of Britt in action:
