Xeinadin, one of the leading professional service practices in Ireland and the UK, has announced that Kilkenny firm Carrigan O’Dwyer Limited, will be joining its growing Irish team.
Founded in 2006, Carrigan O’Dwyer has developed deep expertise advising clients in high-growth and technically demanding sectors, including cyber security, pharmacy, and IT start-ups. With a dedicated team of over 45 staff members, the firm has a strong track record of successfully guiding start-ups through funding rounds, helping established businesses scale, and advising on major cyber security and pharmacy sector initiatives.
In the past two decades, Carrigan O’Dwyer Ltd has become known for delivering tailored advisory solutions that combine technical knowledge with strategic insight, helping clients navigate complex industries and seize new opportunities. Based in Kilkenny City, they are one of the fastest-growing accountancy firms in the Southeast.
Commenting on the announcement, Sandra Clarke, Managing Partner of Xeinadin, said: “Welcoming Carrigan O’Dwyer Limited to Xeinadin is a significant step in strengthening our advisory capabilities in Ireland, particularly across high-growth sectors such as cyber security and technology.
“Their ability to combine technical excellence with strategic thinking, alongside a clear focus on building long-term client relationships, sets them apart. Their expertise will further enhance how we support SMEs and ambitious businesses across the Southeast, working with our existing team in Kilkenny, expanding our presence and service offering to clients in the region.”
Martin Carrigan, Director of Carrigan O’Dwyer Limited, said:
“Carrigan O’Dwyer is 20 years in business, and we felt the time was right to join a larger organisation like Xeinadin. Xeinadin offers the scale and capabilities of a large practice while at the same time prioritising local relationships and an SME first approach, which matches our values as a company.
“Joining Xeinadin brings tremendous benefits, building on the strong foundation we’ve established while unlocking new resources, opportunities, and growth potential. It also opens meaningful career opportunities for our people, giving them exposure to experienced and ambitious peers who will support their professional development.”
This will be Xeinadin’s second office in Kilkenny, with the other located in Lacken House in Kilkenny City. Xeinadin now has 11 offices in Leinster and 32 across Ireland. In 2025, seven firms joined Xeinadin from across the country. In 2026, Xeinadin is continuing its investment strategy aimed at acquiring additional practices and further expanding its presence across Ireland.
