Sam was looking for a way to give back and use her skills for a greater purpose when she first heard of the opportunity to go on a TIE exchange. After getting an e-mail from Wieden+Kennedy Head of Planning, Stuart Smith, she immediately responded showing her interest. Eleven months later, she was boarding a plane to Pretoria, South Africa. Sam would work with the Clinton Health Access Initiative (part of the Clinton Foundation) and the National Department of Health of South Africa. The incredibly challenging objective was to find a way to help stop spreading HIV from HIV positive mothers to their children, to reduce the rate of new infections of the virus.
