CEO

Yann Callaert leads the House with the same values that have defined it for decades. Artistry, precision, and a profound respect for people.

Before joining, he studied International Entrepreneurship and started his career in finance. Adding diplomacy and building new ventures along the way. This breadth of experience instilled both pragmatism and vision, and the conviction that creativity flourishes only when grounded in strong foundations.

He joined Daniel Ost in 2014, first overseeing large-scale projects for royal households, maisons, and private clients. In the years that followed, he focused on strengthening operations and preparing the House for global growth.

Since 2019, Yann has served as CEO, carrying forward the legacy while guiding the House into a new era, where artistry and enterprise evolve hand in hand.

Under his leadership, the House has expanded internationally — with boutiques in Knokke, Amman, and Riyadh, and partnerships with luxury hotels like Corinthia Grand Hotel Astoria and Mandarin Oriental. He has overseen countless weddings, events, and large-scale projects, always balancing heritage with modern systems that allow the team to deliver with precision and grace.

Clients describe Yann as pragmatic, solution-oriented, and always two steps ahead. He sees himself as a partner rather than a supplier, offering honest input, anticipating needs, and ensuring that deadlines and details are never compromised.

Hands-on by nature, he is unafraid to step in at the last moment to make sure everything is perfect, while never losing sight of the bigger picture.

“My role is to make sure creativity can flow freely. If the florists dream it, I’ll find a way to make it real.”

For Yann, leadership is not about titles, but about people, supporting his team in becoming the best version of themselves and ensuring that every client feels cared for and confident. Whether it is a royal wedding or a single bouquet, his goal remains the same: to make every experience meaningful, seamless, and truly worth it.
