We’ve been in business without interruption since 1913, when a young civil engineer named Howard R. Green founded the firm as a sole proprietor. Over the next several decades, the firm grew and established a reputation for technical innovation, community leadership, and accountability to the business concerns of its clients. Mr. Green remained with the firm until his death in 1969, at age 79. Since then, the firm has enjoyed further expansion and growth, diversifying well beyond our historic core business of civil engineering without leaving it behind. A hallmark of our business approach has always been a willingness to evolve as needed to meet the timeliest needs of our clients, and the communities where we live and work.

Today’s HR Green, Inc. is a confluence of Howard R. Green’s proud legacy with other successful companies who have joined us to form one strong organization.
