Top 15 Irish Private Client Managers and Advisors 2026

Citywealth presents its Top 15 Irish Private Client Managers and Advisors 2026, a snapshot of the people currently shaping how serious money is handled in Ireland. From tax structuring to succession planning, these are the advisers brought in at moments that carry real consequence, exits, disputes, relocations and generational handovers.

As Seamus Heaney, Ireland’s Nobel Prize-winning poet best known for Digging and Mid-Term Break, wrote, “between my finger and my thumb the squat pen rests; I’ll dig with it.” It is a line about precision and doing the job properly. In Ireland’s wealth world, that same standard applies, but with sharper edges. As investor Dermot Desmond has shown over decades, outcomes are driven by timing, structure and judgement, not sentiment. The advisers on this list sit squarely in that space, where decisions taken early tend to matter most.
