Sara joined The Data School from an entrepreneurial background, having started her first business at the age of 18 and later graduated with a Business Enterprise degree. It was through her own business experience and working with other organisations, that she discovered the power and importance of analysing and understanding data. Keen to learn more, Sara attended a Meet & Greet event hosted by The Data School where she discovered the infinite possibilities of what Tableau and Alteryx can achieve. She was encouraged and inspired by The Data School’s ethos and knew this was a perfect place to pursue a career in data analytics.
