Seán Mulleady, CEO and Principal

Seán Mulleady is co-founder and co-owner of conceptcsi with more than 25 years’ experience from a diversified background of Construction, IT and Management Consultancy in the United States and across Europe. He spent his formative years in England, where his father founded and ran a successful national construction firm, before the family returned to Ireland. Sean later attended Greenwich University, London where he studied computer science before immigrating to New York in late 1992. The saying “An apple doesn’t fall far from the tree” could not be more fitting as Sean clearly shared his father’s passion for construction along with an unrelenting entrepreneurial spirit. A little more than two years after arriving in New York, Sean together with his long time business partner Tom Moroney, founded their first business. Since 1995, Sean’s vision and leadership has helped grow the organization from a lone, startup business to an exclusive construction group with global resources and capabilities, renowned for its client relationship focus and boutique-style service.     Tommy Moroney
