Oosterberg – New General Manager at Royal Oosterberg
Effective October 1, 2025, there will be a significant change in our management team.
After five years, George Rietbergen will hand over the reins to Seine Ligtenberg, who will take over as our new Managing Director.

George led Oosterberg through a challenging period: COVID-19, price pressure, and a rapidly changing market. Under his leadership, our market share grew and we made significant strides in broadening our offerings and increasing our customer focus. We thank George for his unifying leadership and entrepreneurial spirit throughout these years.
Flip Oosterberg : ” George has been instrumental in guiding Oosterberg through challenging years, and we’ve experienced growth together with Oosterberg. We’re grateful to him for that. With Seine on board, we’re ready for the next phase, where we’ll continue to grow with customer focus, courage, and a healthy, future-proof Oosterberg.”
Seine brings extensive experience from commercial roles at ING and Rabobank, among others. He deliberately chose Oosterberg for its family culture, strong foundation, and growth opportunities.

Seine Ligtenberg : ” Koninklijke Oosterberg is a family business through and through, with a customer-centric approach and a long-term focus. Together with the team, I want to build on the foundations laid by Flip and George. We’re entering the next phase of growth, where we’ll expand our markets and serve our customers even better – digitally where possible, in person where desired. “
Our strategy remains unchanged. Continuity, customer focus, and collaboration will continue to form the foundation for further growth in the coming years.
