I write and edit documentation for clients in financial services, supported by 30 years of risk and regulatory experience at leading banks.

I do copy editing and proofreading for professional and academic clients, focusing on finance, business and language.

Risk, regulatory, governance, strategy, policies, procedures, manuals, audit, marketing, project, training, educational, web content, books, journals, research: all done to the same professional standards.

My targets are to always write and edit in clear business English, and to present clearly and effectively.

I am a visiting lecturer at City, University of London and do customised training and mentoring in business writing.

All prices depend on the type of job, complexity and turnaround time. I quote by the day, hour, or thousand words depending on the job.
