Who We Are

Lawyers who are easy to deal with and understand all sides to a transaction

AMOSS LLP was founded in 2012 by Alan Adams, Dan Murphy, John O’Sullivan and Gavin Simons. Having known each other for many years, the founders realised they had a similar attitude, work ethic and vision and together could provide comprehensive legal services to commercial clients that was different to other law firms. 

The firm's key differentiating quality is that clients always have access to a Partner receiving a fast turnaround, value for money, delivery on promises, and practical commercial advice from an experienced, down to earth team of lawyers.

Since starting on this journey with 15 staff in 2012, AMOSS has grown to over 80 staff making it one of Ireland’s most recognised and successful commercial law firms.

In 2016, AMOSS joined Interlaw, a long-established global network of pre-eminent independent law firms located in  over 150 cities with 8,000+ expert lawyers around the world, as its sole representative law firm in Ireland. John O’Sullivan is on the Board of Directors and Chair of the EMEA region of Interlaw.
