Our Partners at Duignan Carthy O’Neill don’t believe in short-term thinking and as such they are fully committed to long-term client relationships with the provision of excellent service.


Every client has a direct relationship with one or more of the Partners, ensuring an efficient, professional and personal service across the full term of engagement, which may span a number of years or even decades. This Partner-led professional service, from our team of industry experts who are committed to seeing their clients thrive has led to our company being seen by clients as strategic partners rather than external contractors. As a result, we are asked by clients to advise on major decisions and, where appropriate, asked to sit on their boards.


The Partners head up a team of senior managers and qualified professionals. It is company policy to employ highly qualified, senior staff, and we encourage continuous education and professional development at all levels.
