The integration of purpose and professionalism

After 25+ years advising Boards on complex financial reporting, governance and risk, I am now focused on securing a permanent, interim or contract role where I can bring that experience directly into a listed or large private group. I am immediately available.

My background combines deep technical accounting expertise (IFRS, US GAAP and global transaction management) with hands-on work in sustainability reporting and regulatory readiness, including CSRD, ESRS and wider governance frameworks. I have spent the last few years applying financial-grade discipline to non-financial reporting, helping organisations build controls, structure disclosures and prepare for assurance.

I am now looking for a role where I can apply this combination of skills within a single business - strengthening reporting, improving governance, shaping transition planning or building out sustainability capability. I am open to financial reporting, sustainability reporting, risk, governance or hybrid roles that value a blend of technical depth, strategic thinking and the ability to deliver quickly.

I am based in Windsor and seeking roles in Central London or the M4/Thames Valley corridor.
