OUR STORY

Our foundation is built on experience and dedication.

Errigal was founded over 25 years ago by Damien Treanor and Cormac McCloskey.

With more than 35 years of experience in the UK, Ireland, and internationally, Damien has fostered a family-oriented culture of care, support, and trust, driving Errigal’s commercial success. He is passionate about people, community, and industry development, and his leadership is the cornerstone of ‘The Errigal Way.’ His values are embodied by the team, who are dedicated to delivering excellence, no matter the size of the challenge.

Cormac, known as the operational backbone of Errigal, has led the successful execution of numerous complex projects. His can-do attitude and ability to build long-term, trusted partnerships have made him a go-to leader for some of the world’s top construction companies.

Together, Damien and Cormac bring over 60 years of industry experience, having cultivated strong, loyal relationships that have been key to Errigal’s success and will continue to shape its future.
