Our teams share their experiences
“Since my arrival at Terresis Agriculture in October 2022 as Zone Manager LATAM, my journey has been marked by several developments. In December 2023, I took charge of the Americas zone, thus covering North America and LATAM. After an integration period in Dinard, I moved to Bogota until May 2025, before returning to Saint-Malo where I am currently based.
What motivates me at Terresis are the daily challenges, customer satisfaction, excellent relationships with our clients and colleagues, as well as the headquarters’ infrastructure and quality of life. Since my arrival, I have developed important skills in sales management and team leadership in a multicultural international context, as well as technical product skills.
Terresis is a company offering many possibilities for evolution at different levels, with great autonomy allowing the proposal of new projects. In three words, I would describe my experience at Terresis as international, development-focused and challenging, and imbued with great responsibilities.”
