Who We Are


After graduating from Christ’s College, Cambridge and qualifying as a barrister, Adam worked for JP Morgan for 24 years, where he ran JP Morgan’s Private Bank and Institutional Client business in Europe & Middle East. In the 1990s, he was head of JP Morgan’s London Offices, CEO of JP Morgan Securities Ltd, Co-head of Corporate Finance and Chief Operating Officer in Europe. In 2000 Adam co-founded, with William Drake, Lord North Street – Private Investment Office, which they started in Adam’s house in Lord North Street, Westminster, and developed into an award winning business. In 2014 they sold the enterprise to Sandaire. In July 2016, they left and created Owl Private Office as a new business advising wealthy families and trustees on how to optimise their investment arrangements and obtain the best results from the investment industry and other services.
