The O’Connor Companies
Founded in 1904 as a builder of stone and masonry buildings, the O’Connor Companies has grown to become the go-to construction resource for academic and industrial clients, mechanical installations, comprehensive safety services, and maintenance for a host of clients across the United States.
For four generations of O’Connors, and under today’s leadership of Thomas O’Connor, III, the company is unwavering in its commitment to always do what is right for the client.
