Reviewed on 24.02.2026

Julien was a fantastic addition to our Category Management team in the Netherlands. Highly professional, with deep CatMan expertise and a great ability to build customer relationships, he quickly became a trusted partner internally and externally. During his assignment in Oral Care, he delivered a strong set of projects with a clear results presentation to our management board, while also uplifting our team’s skills and ways of working. He led several customer meetings with confidence and impact, building rapport from the very first interactions. I truly enjoyed working with Julien and highly recommend him for any CatMan or customer‑facing role.
