Joe Stokes

Joe’s first experience with Data Analysis came in his final year of University where he studied a Year in Computing and underwent a Data Analysis dissertation. Joe’s first job after University was working within the Football Association – a job in a sport he loves. However, it was an admin role and he quickly became disillusioned with the lack of challenge the job offered.

Having enjoyed the Data Analysis project, but fearing a lack of real technical knowledge and experience, the discovery of The Data School seemed the perfect start. He really enjoyed the intuitive nature of Tableau and marveled at the endless possibilities. He is really excited to start training and see where the journey takes him.
