Van Seeters will report to H&K EMEA CEO and chairman Sally Costerton and will sit on the firm's EMEA council.
The agency confirmed that van Seeters will look to bolster H&K International Belgium's public affairs team with new hires.
'In recent months I have spoken to clients, candidates and other senior influencers about what they believe is missing on the Brussels scene,' said Costerton in a statement. 'Without exception they have said that what they are looking for is a firm that can successfully connect policy and communications issues to their business goals. Of all the people I have worked with in my career, I can honestly say Jeroen has few peers when it comes to his business focus and client- centric approach to consultancy.'
Van Seeters is a Dutch national with almost 20 years experience in international comms.
