John O’Callaghan Ltd was established in 1983 and incorporated in 1992 by John O’Callaghan senior, a former inspector of taxes with the Revenue Commissioners.
Since its establishment, the business has built itself into a leading accountancy, tax consultancy and business advisory practice, yet always maintained its objective of placing its clients first by providing them with the best possible advice and assistance to grow their business.
The business has grown and evolved over the years and credits this growth in part to having an experienced team and employing the best practice technologies available for it and its clients.
This has ensured that any client queries can be dealt with promptly and efficiently.
