Niall O’Keefe

CEO @ National Association of Building Co-operatives (NABCO)

O’KellySutton delivered corporate governance and business compliance advisory services to our organisation in a very professional and insightful manner. They have a deep understanding as to what it takes to be successful in business and how to improve business performance standards.


Peter Brady

CEO @ Equilume

As a start- up company we were blown away with level of hands on support we received from O’KellySutton. The time and interest they took in understanding our business, assisting us in developing our business strategy and business model, giving us clear practical business advice, preparing and introducing us to potential investors, was critical in ensuring we were able to navigate the difficulties that are part and parcel of a fast growing start up. They have become an integral part and trusted adviser to our business.


Sven von der Heyden

Chairman, Von der Heyden Group

At all times we were impressed by the diligent way in which Pat Sutton and his colleagues carried out their due diligence, how quick they were to understand our complex group with 400 employees, active in 3 different countries. A striking fact was the constructive and objective way of working with us, even when they were finally retained by an investor who successfully invested into our Holding Company. We have no hesitation in highly recommending O´KellySutton as Accountants and business consultants or for any complex financial or due diligence work


Richard Dunne

Managing Director, Granite Concepts

O’Kelly Sutton have been our accountants and auditors since we commenced business in 2002. During this time, O’Kelly Sutton have been very good for my business and have played an important role in our success and have provided us with a lot of expertise in many areas. On a personal level, I have found Pat Sutton a very good business advisor and have used his expertise in matters relating to accountancy, tax, business development & strategy and personal finance. His pragmatic and objective approach to problem solving has stood to me over the years and usually allows me to make the right decision at the time.


John Cleary

Naas Health & Fitness Leisure Centre / Bresc Group

OKellySutton have provided accounting and strategic business services to various, and diverse businesses we are involved with over the past 20 years. The term business “partner” is bandied around a lot, and often used very lightly, but it is safe to say that it is the only way to describe our experience with OKellySutton. They have always acted proactively in our best interests and continually surprise us with their level of understanding and depth of knowledge across industries. Tough business decisions have been presented more and more in recent years but one major reassurance is having the experience and expertise of Pat Sutton, Patrick O’Rourke and their team on hand


Martin Horan

Founder and Former Managing Director BioTector Analytical Systems Ltd.

O’KellySutton began advising BioTector as a start-up in the late 1990’s on business strategy and financial planning. The success and growth of the company resulting from the initial programmes led to a number of further strategic development programmes run by O'Kelly Sutton over the following 18 years. When the Shareholders were approached about a possible company sale it was only natural we would appoint O’KellySutton for advice and guidance on the transaction. O'Kelly Sutton helped to establish a fair but aggressive market valuation and produced a comprehensive Information Memorandum which became the foundation document for the successful sale of the company in 2014. O'Kelly Sutton's help and support to the Shareholders throughout the complex discussions was invaluable and contributed significantly to the successful outcome of the negotiations.
