While working in the life sciences sector as an engineering buyer, our Founder and CEO Niall Corrigan saw firsthand that the supplier-customer relationship was not working as well as it could do. A lack of focus on organisational goals and a poor understanding of the business value of engineering projects was leading to suboptimal work.

He knew that if companies engaged at a deeper level with their engineering partner, better solutions would follow which met organisational goals. And with that, Dolmen Engineering was born and our company has gone from strength to strength ever since. Headquartered in Castlebar, Co. Mayo with offices in Dublin, the U.K. and Belgium, we now employ 70 people across many engineering and design disciplines.
