About us our story

“We offer a service that is modern and genuinely different yet delivered in a dependable manner you would expect from a firm of Chartered Accountants in business for over 25 years”

The firm was founded by Sean’s father, John O’Rourke, in 1989 and we continually strive to blend the traditional values of a family business with modern, technology driven services. Sean joined the firm as partner in 2007 having worked for top 10 accounting firms in both Ireland and Australia. In 2009 Sean O’Rourke became our managing partner and we embarked on a journey to modernise the way accountants serve their clients in Ireland. Although Ireland in the midst of a recession at the time our message resonated with young, tech savvy business owners and we have grown strongly over this time.
