Legacy Pride…90+ Years of History!
In 1926, the firm of Forster and Wernert was formed to provide engineering services to a variety of private and public sector clients. In subsequent years the firm grew, added architecture to the engineering disciplines offered to its clients, and changed its name many times as new partners came into the firm. In the 1950s, when the firm was known as Sanzenbacher, Miller and Brigham, its expertise in highway and bridge design led to a number of major projects with the Ohio Department of Transportation (then known as the Department of Highways), the Ohio Turnpike Commission, and the Michigan Department of Transportation (Michigan State Highway Department). In the following years, the firm expanded into traffic engineering, port and rail facility design, and site development; its architectural practice was discontinued. The firm then became known as Dansard Grohnke Long Limited, Ltd. in 1977 and operated under that name for close to thirty years. In 2006, the company became DGL Consulting Engineers, LLC. DGL continues to enjoy a successful civil engineering practice, and we are proud of our record of providing professional services to public and private sector clients continuously for over 90 years!
