Simona Loffredo

After 3 years working in management consulting in Milan, Simona has decided to move to London to continue her professional career in data analysis at the Data School. That’s what she was dreaming of when she graduated in Mathematics in 2012: learning about the world of data. The discovery of the Data School and Tableau made her realise that this was not a dream anymore!

In her spare time, Simona likes doing pilates and swimming. Moreover, she’s passionate about wines and she’s member of the Italian Sommelier Association from 2014.
