Jon-Luke, a Chartered Accountant from South Africa — CA(SA) — and a member of the Cayman Islands Institute of Professional Accountants (CIIPA) – is a Senior Manager in the Advisory practice at HLB Berman Fisher. He has over 13 years' experience across financial advisory, audit and accounting and has worked with clients in financial services, not-for-profit organisations, retail, real-estate and general operating businesses, and is comfortable moving between the reporting demands of a regulated entity and the day-to-day realities of an owner-managed business.

He began his career in 2013 in East London, South Africa, as a financial advisor specialising in investment management, building and managing a portfolio of individual investor clients. In 2017 he moved to Cape Town, where he spent five years in audit at Nexia Cape Town. Alongside his client work there, he led the redevelopment of the firm's audit processes and systems, replacing manual workpapers with a modern platform — his first sustained work in automation, and the point at which the technical side of the profession became a genuine interest rather than a necessity.

He relocated to the Cayman Islands in 2022 and spent four years at Grant Thornton, progressing to manager of the firm's newly formed corporate audit division. Building the division meant implementing new tools, assisting in the writing the procedures, templates, and review standards – aligned to global standards – which the team now works to, and also training the staff who use them.

He joined Berman Fisher in mid-2026, where his focus is the design and deployment of AI and other automation tools — improving how the firm itself works, and helping clients apply the same thinking to their own finance functions.

 His work tends to start with the same question: where is time being spent on something that does not need a person doing it? The answer is often a well-chosen tool, a reworked process, and someone documenting it properly. He is used to running several complex engagements at once and to the practical constraints that come with implementation — budget, buy-in, and the fact that any new process has to survive contact with a busy month-end.
