Testimonials

We first used the services of O'Brien & Co. when our business had just started in 2002. At that time we were in start-up mode and required services that a small accountancy practice could provide at a reasonable cost. As our business grew, O'Brien & Co. adapted and expanded their service offering to match our new needs.

Tom O'Brien and his team have demonstrated exceptional professionalism combined with a personal touch that larger firms simply cannot match. They have been an integral part of our journey, providing not just accounting services but genuine business advice and support.

We would have no hesitation in recommending O'Brien & Co. to any business looking for a dedicated, knowledgeable, and approachable accountancy partner.

Tom O'Brien is the most personable, professional and practical accountant I have ever had. It is a pleasure to do business with this intelligent firm.

What sets O'Brien & Co. apart is their genuine interest in understanding your business and your goals. They don't just process numbers — they provide insights and recommendations that have directly contributed to our growth and profitability.

Their response times are excellent, their fees are fair and transparent, and the quality of their work is consistently outstanding. I have recommended O'Brien & Co. to several colleagues, all of whom have been equally impressed.

Business Owner

We switched to O'Brien & Co. three years ago after becoming frustrated with our previous accountants' lack of responsiveness. The difference has been remarkable.

Tom and his team are always available when we need them — questions are answered promptly, and nothing is ever too much trouble. They have helped us restructure our business more tax-efficiently and have saved us significant amounts through proactive planning.

What I appreciate most is their ability to explain complex financial matters in plain English. They make you feel confident and in control of your finances. I couldn't recommend them more highly.

Managing Director, Retail Business

As a construction business, our financial affairs are complex with multiple projects, subcontractors, and RCT compliance requirements. O'Brien & Co. have been our accountants for over a decade and have never let us down.

Their knowledge of the construction sector and relevant tax regulations is second to none. They handle our payroll for 40+ employees, manage our RCT returns, and provide monthly management accounts that give us clear visibility of project profitability.

Beyond the technical competence, they are genuinely nice people to deal with — professional, responsive, and always willing to go the extra mile. A trusted partner to our business.
