Colliers announces further senior strategic hires

30 04 20 london offices

James McAdden has joined Colliers as a Director in West End Capital Markets and Associate Director, George Clutton returns to London from Tokyo to join the International Capital Markets team. 

These appointments are the latest in a string of announcements from Colliers and closely follow the news of Simon Glenn joining as new Head of London Capital Markets, last week.

With more than 15 years’ experience in the sale and purchase of mixed-use sites and investments within Central London, McAdden has a deep network of contacts within the Central London commercial property market. Formerly a Partner with Montagu Evans, McAdden is returning to agency-side following a short period overseeing a major planning application for his family commercial property business.

“James brings a raft of experience to our West End team and perfectly complements our wider transactional capabilities across the London market,” said Tony Horrell, Colliers’ CEO UK & Ireland. “It’s an exciting time for Colliers in London and with these strategic hires, we are in a robust position to take our London offering from strength to strength.”

McAdden added: “I am excited to return to agency life as part of Colliers’ dynamic West End Capital Markets team. London represents a rapidly-changing market, full of opportunity, and I look forward to working with this experienced team of specialists to offer the very best service to an international client base.”  

Further bolstering Colliers’ international capital markets capabilities in London, Associate Director George Clutton returns to the UK after almost three years with Colliers in Tokyo. Clutton has joined the International Capital Markets team and will work primarily with overseas clients, harnessing his knowledge and contacts in the Japanese market, in particular, to advise on the acquisition and disposal of commercial real estate across London. 

Andrew Thomas, Head of International Capital Markets, added: “It’s great to have George back with us in London. The contacts and experience he has gained during his time with our colleagues in Tokyo will be invaluable as he returns to the London market.”
