Based in Galway, DEACY GILLIGAN LTD (DGL), Chartered Accountants, Business and Taxation Advisors, are committed to providing quality professional services of the highest standard to our clients.

About DGL

The Company was formed in 2010 on the merger of two prominent Galway Accountancy practices, Deacy & Associates and Grealy & Co. Both former practices shared a common ethos, and this led to a rapid integration of the firms into the new entity.
