Four generations serving Northeast Georgia since 1938.

The Dunahoo Family has a tradition deeply rooted in land surveying that spans three generations. The tradition started in the early 1900s when L. A. (Lucious) House made land surveying his primary occupation and served as County Surveyor in Barrow County, Georgia. Horace Lucious (H.L.) Dunahoo, named for his uncle Lucious House, had a great fascination with the staff compass and began learning the trade as a young school boy. In 1938, H. L. began his career in land surveying. He was elected to the position of County Surveyor and opened his office in the Barrow County Courthouse. Governor Ellis Arnold appointed H. L. Dunahoo to survey the county line dividing Gwinnett and Dekalb Counties. For several months he surveyed the thirty two mile line, defined as the Old Hightower Indian Trail, and prepared maps to define the line for future generations. Until his death, H. L. Dunahoo was a well respected surveyor in both Georgia and South Carolina.

In 1963, at the early age of 48 years, H. L. Dunahoo died in an automobile accident. At the time his son, William Terrell (W. T.) Dunahoo, who had already worked for years in the surveying business, was attending college at Georgia Tech majoring in Civil Engineering. He returned home to continue the family business of surveying and was appointed by J. B. Lay, Chairman of the Barrow County Board of Commissioners, to fill the unexpired term of his father as County Surveyor. He continued his studies at Georgia Tech and obtained his degree in 1966. He became a Registered Land Surveyor in Georgia in 1968 and went on to become licensed in South Carolina. W. T. constructed his office in Winder in 1969 and has remained in that same location, making several additions through the years.

In January of 2021, the newly constructed bridge on Highway 11 at the county line of Barrow and Walton Counties was officially dedicated and named the Horace L. Dunahoo Memorial Bridge.  The ceremony was conducted by Georgia House Representative Terry England, and the bridge was dedicated per Georgia House Resolution 444.  The new bridge replaced the bridge where Mr. Dunahoo was tragically killed in a car accident in 1963, while serving as county surveyor of Barrow County.
