Andrew Brixey-Williams BA (Hons) PGCE, DipPFS, FRSA

Managing Partner


After working for three different firms since 1990 I set up Fiduciary Partners in 2009 with Diane, with whom I've worked continuously since 1993. My particular interests are the Prestwood financial planning system and investment planning. I am a member of the Chartered Insurance Institute and Personal Finance Society, holding the DipPFS and working steadily towards Chartered Financial Planner status.


I hold specialist qualifications by examination at Advanced Diploma, Diploma and Certificate levels in areas that include Investment and Risk, Taxation, Trusts, Pensions, Retirement Planning, Group Risk, and Supervision & Management.


I started life as a musician, studying under Wilfrid Mellers at the University of York, and privately with Elisabeth Lutyens and Oliver Knussen. After a stint teaching in the maintained sector I started retraining as a financial planner in 1990.


Still a keen pianist, with an avid interest in contemporary music, I also support the musical lives of my two sons. I'm married to a fine artist. My other interests include Buddhist philosophy & meditation and South East Asian culture. As a Fellow of the Royal Society of Arts, I can also meet you centrally at the RSA's beautiful headquarters just off the Strand.
