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 30 years”

The firm was founded by Sean’s father, John O’Rourke, in 1989 and we work hard to ensure we blend the traditional values of a family business with a modern, technology driven service. Sean joined the firm as partner in 2007 having worked for top 5 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 was in the midst of a recession at the time our message resonated with tech savvy business owners and we have grown strongly over this time.

Our People

We have a team of eight people in our offices in the centre of Killarney but our clients come from all over Ireland, overseas and as far away as New Zealand!

Seán O’Rourke FCA

Sean is our Managing Partner, he is a graduate of the University of Limerick and a Chartered Accountant. Sean has worked with KPMG providing accounting and tax services to some of the largest multinational companies in Ireland but he wanted a bigger challenge……to provide the same quality of service and advice to some of the smallest companies in Ireland! Sean is a technology lover and is obsessed with finding better and more efficient ways of doing things. linked
