Merry Mullen is the accounting representative of Alliott Global Alliance in Ireland.
Merry Mullen is an independent, partner-led firm of chartered accountants and tax advisors based in Dublin 2.

Established in 1945, the firm has been guiding Irish businesses, family enterprises and international investors through every stage of their journey—from start-up and growth to succession planning and exit.

The firm's partners and senior leadership team all bring experience gained at top 10 accountancy firms, providing clients with exceptional technical expertise, commercial insight and a broad range of advisory services. Combined with the agility of an independent practice, Merry Mullen delivers high-quality, partner-led advice without the overhead, hierarchy or divided attention often associated with larger firms.

By building long-term relationships and taking the time to understand each client's business, objectives and ambitions, Merry Mullen provides tailored support that helps clients achieve sustainable success. This client-centric approach has fostered relationships spanning decades and multiple generations and was recognised with the firm's award as Medium Practice of the Year at the Irish Accountancy Awards 2025.
