Gustavo Griff

Born in Lisbon in 1993, he became interested in the world from an early age. Politics and law proved to be his main areas of analysis. Attentive and curious, he emigrated to the Netherlands while still in high school. This experience gave him a broader and more functional perspective on the world of work. He graduated in Law in 2021, completed a postgraduate degree in Conflict Mediation in 2023, and has been a lawyer registered with the Brazilian Bar Association since 2024.
