Sarah-Sternberg-Songa-Design.jpeg Looking for a career change a few years back, Songa Designs co-founder Sarah Sternberg found inspiration in her volunteer work in east Africa. Sternberg had been thinking about making lasting social impact in a for-profit business. Her travels sparked the idea to create a contemporary jewelry and accessory design line using only locally sourced materials from Rwanda. Today, the company uses 150+ local artisans and staffs 10 in the region.
