Stephen Antram

Stephen has successfully sold these businesses in 2022 to a Sussex based private equity firm.

Edward Docherty

Head of Private Investment Office

Edward has over 35 years' experience advising the UK government, FTSE100 boards and the leading entrepreneurs in the UK. He has worked in the Big 4, at several of the world’s leading investment banks, and has started, built and sold his own business. In his last role, he spent 17 years advising the largest and most complex clients at Barclays Private Bank on their wealth management needs.

His experience of multiple market cycles has given him a very strategic view of wealth management, an ability to see the wood for the trees, and the skills to communicate this, in plain terms, to busy entrepreneurs.

Edward believes that many houses in the wealth management industry have an inherent conflict of interest in that they seek to manage clients’ investment assets in-house, irrespective of whether theirs is the best solution. In the Private Investment Office, Edward works alongside Will and Rory to provide a multi-family office service that is purely advisory, unconflicted and that sits on the same side of the table as its clients.

Edward has an LLB (Hons) from the University of Glasgow and qualified as a Chartered Accountant.
