Started in 1957 by Jack and Bill O’Shea, Shamrock continues to be a closely held business, but has grown to have the financial and technical strength necessary to offer complete and dependable services to our wide range of customers. Our projects have varied from the depths of Chicago’s Deep Tunnel to the tallest skyscrapers, with experience in Design/Build, LEED and sustainable energy solutions. The hallmark of our business relationships is trust, which has been built largely through long-term commitments among customers, suppliers, and subcontractors. Our employees say Shamrock Electric is a great place to work, where employees exhibit pride in what they do and enjoy the people they work with. We truly believe our people set us apart from every other contractor. In a world of frequent change, Shamrock Electric continues to be a consistent source of innovation, effective project management, safety, and technological expertise.
