After her scientific high school degree, Géraldine did a DUT GEA (Gestion des Entreprises et Administrations) at the University of Savoie in Annecy. This was followed by a year of work-study and two years of work on a fixed-term contract.
She then joined the accounting department of CAF de l'Isère in 2002 where she was mainly in charge of supplier accounting and investment monitoring. After 20 years of working in administration, she felt the need to discover new horizons which led her to join BeFC.
