Brad Unsworth​

Managing Director

Brad arrived in the Netherlands in 1991 and subsequently took over his father’s business.  After spending more than 40 years in the industry, Brad has justifiably taken a step back from the day-to-day management at Unsworth.  With his invaluable knowledge, he remains a key part of the organization and an important sounding board for the rest of the team.

These days, Brad spends more time back in his native Nova Scotia finally giving his neglected sailboat some attention! Brad also enjoys spending time with family and teaching the grandchildren how to identify good wine and play golf badly. 

Duncan Rennie

Managing Director

With the rapid increase of compliance demands over recent years, a significant part of Duncan’s role has been to improve the compliance function across both offices and ensure it continues to protect Unsworth and the clients we serve.  He has simultaneously led the drive to expand the business lines and evolve the strategic direction at Unsworth. 

When Duncan has some downtime, he enjoys cycling, football and spending time at galleries and museums.
