Reliable, professional and focused on our clients, DBASS has been helping businesses succeed for over 30 years.

"At DBASS, we believe accountancy is about more than numbers — it’s about supporting people, businesses, and communities to grow with confidence. Our goal is to give clients clarity, trusted advice, and the space to focus on what they do best, while we take care of the rest." Michael Byrne, Director.
DBASS was founded in 1988 by Dermot Brennan, a Chartered Accountant with a clear vision – to go beyond traditional accounting and become a trusted partner in business growth. What began as Dermot Brennan & Associates has evolved into DBASS, a firm built on experience, insight and a genuine commitment to helping businesses like yours thrive.
We don’t just provide accounting and advisory services; we help you make informed decisions, seize opportunities, and navigate challenges with confidence.
We believe good communication builds great partnerships. That's why we're always accessible and quick to respond. Our clients know help is only ever a call or email away, and that we'll deliver clear, practical advice when it matters most.

Our business is built on relationships that have been nurtured over our 30+ years in business. It has always been our priority to get to know our clients, to understand what is important to them professionally and personally. By listening to our clients, we truly work together towards their goals.

We believe that integrity and ethical behaviour are central to maintaining our reputation, and we take our responsibilities in this area very seriously. We provide an objective and confidential service designed to address our clients’ individual needs.
