Damian Donlon, CEO, dulann

"I've known Liam O'Connor for over 15 years and have had the pleasure of working with him professionally for the past five. During that time, Liam has become an invaluable extension of our team and fits into our business seamlessly.

Through OEI, Liam manages our ISO 27001, ISO 9001 and ISO 45001 management systems, serves as our Data Protection Officer, and provides strategic advice on compliance, governance and risk. His technical knowledge is second to none, but what truly sets him apart is how he applies it. Liam doesn't just advise, he guides. He works alongside us to remove risk, improve performance and ensure we achieve the right outcomes in a practical, business-focused way.

Compliance can often seem complex and burdensome, but Liam has an exceptional ability to simplify it. He translates technical and regulatory requirements into clear, manageable actions, making the entire process feel straightforward. Quite simply, he makes compliance as easy as booking a flight.

Beyond his expertise, Liam is an absolute pleasure to work with. He's approachable, dependable, responsive and genuinely invested in the success of the businesses he supports. He doesn't behave like an external consultant. He fits into our team seamlessly and is regarded as one of us.

I have no hesitation in recommending Liam O'Connor and OEIRL to any organisation looking for a trusted partner in compliance, information security, quality management and data protection. His expertise, integrity and hands-on approach are exceptional, and I couldn't recommend him more highly."
