A new era begins for Dafferns in January 2025 as Martin Gibbs, the firm’s Managing Partner for the last 17 years steps aside to pass the baton to Brian Jukes and Geoffrey Cox
Joint Managing Partners
Brian Jukes and Geoffrey Cox take over as Dafferns new Joint Managing Partners, with Geoffrey focussing on internal practice management, finance, systems and compliance and Brian focussing on the external, public and client facing side of the role.
Brian Jukes
Brian Jukes, is a hugely experienced trusted adviser to clients and the Head of Corporate Tax, with extensive experience in cross border taxes, R&D tax credits, corporate finance and business valuations. Hugely respected as a tax advisor, Brian has deep connections with AGN International member firms around the world, helping Dafferns clients do business worldwide.
There is, and always has been, something about the ethos of Dafferns that engenders deep loyalty to the firm. I am very proud to have been a part of maintaining that culture over the past 20+ years and welcome the opportunity to pick up where Martin has left off to lead the firm forward with that same strong sense of community. In a turbulent world we need stability, integrity and certainty wherever we can find it and I will be working hard with Geoffrey to ensure that Dafferns remains a supportive, welcoming firm for our staff and a valuable, trusted resource for our clients.

Geoffrey Cox
Geoffrey Cox, brings a wealth of experience as Head of Audit and a specialist in charities and not for profit organisations. He has a passion for developing new practical processes and procedures for Dafferns and clients, leveraging cloud technology.
Having been with Dafferns all my working life, that is 30 years, I have a deep passion for what Dafferns stands for, its ethos, and ensuring its continued success and maintaining our exceptional client service.

Our new Chairman
Martin Gibbs
After 17 years as Dafferns managing partner, in 2025 Martin has become our new Chairman, supporting Brian and Geoffrey to ensure a smooth succession, assisting with strategic planning, facilitating effective communication and representing the firm.
I have had the privilege of leading Dafferns as Managing Partner for the last 17 years and have seen huge changes and growth within the firm, including our big office relocation in 2010, our adventures travelling the world with AGN International since 2015, leading the firm through the pandemic and the new business world that emerged post pandemic.
Now it is time to pass the baton to Brian and Geoffrey as I prepare to transition into retirement later in 2025.
Martin Gibbs – Chairman
