I am a freelance copywriter and editor specialising in financial sector content: including blogs and articles, technical authoring (model documentation), strategy, risk, regulatory, governance, policies & procedures, manuals, white papers, audit, project, training, marketing/promotional material, and websites.

I do traditional copy editing and proofreading for professional and academic clients outside the financial sector. I also do fiction developmental editing for indie authors.

I worked in the City for 30+ years in financial risk and regulation. So while still relatively new to copywriting as an industry, I have many years of experience drafting and editing complex financial content, with a growing portfolio of clients in my freelance business Prism-Clarity.

I have degrees in English Language & Literature (University of Newcastle upon Tyne) and Economics (University of London). I offer meticulous, professional copywriting and editing services, using clear business English. Prism Clarity: transforming your content and bridging the gap between finance and language.
