I have connected with Arthur though our work at ChangemakerXchange supporting some of the world's top young changemakers. Arthur and the team at AfroSaude have shown incredible dedication and creativity to tackle a deep-rooted and systemic issue in racism and inequality in Brazil's health system. His entrepreneurial approaches at finding the leverage points in the system and at mobilising local community members are hugely impressive. Arthur also comes across as a humble and collaborative character and is always very responsive and reliable. I would highly recommend him and his work!
