Company Profile

Riordan O'Sullivan and Co are one of Londons longest established accounting firms, having started their business in 1968. As specialist accountants, statutory auditors and business advisors they work with a wide range of clients, yet bring a deep level of expertise and experience from working with companies in the construction, property and waste management sectors.


Riordan's had no real web presence online or on social media, and in late 2020 they felt it was time to develop a website that spoke of the longevity and experience that the firm had developed. Via brand workshops, copywriting workshops and website development, Prosper was tasked with positioning the firm as the credible and deeply knowledgeable experts they have become over the last 50 years.


An initial brand strategy workshop with Prosper, followed by a copywriting workshop ensured that Riordan's message was on-point and communicating the company's strengths to the correct audience. A unique and bespoke responsive website was designed, with embedded content feeds, contact forms and social media links that allow website visitors to quickly understand Riordan's offerings and reach out to them via various contact methods.
