CEO of Diefendorf Capital, Roey Diefendorf, has removed his family name from the company after 139 years.
The wealth management boutique will now be named 3 Dimensional Wealth Advisory and Diefendorf will keep his role as chief executive.
He said: "What we are working on today is much bigger than Diefendorf. Our approach to managing personal, financial and social wealth is a departure from traditional wealth management. It required a re-engineering of our firm."
