In 2009, Duco made the move to real estate. Before that Duco held various commercial positions in the area of project design. Duco worked at Colliers for seven years where he became the commercial intermediary between clients and consultants. When Duco joined CBRE in 2016, all the pieces of the puzzle fell into place. As a Senior Consultant of Advisory & Transaction Services, he does more than just focus on his own residential area in Rotterdam. He can also successfully supervise the projects he acquires from customers, and thus contribute to the successful completion of a housing project. Duco works in the Tenant Representation department and assists and advises tenants with housing queries. Often these types of contracts include assistance from multiple CBRE business lines. Duco usually holds a leading role within the project team.
