William D. “Bill” O’Hara, RPLS, LSLS

Bill O’Hara began his land surveying career in 1981 as a chainman on a surveying crew following his honorable discharge from the United States Air Force. He spent the next 18 years completing his land surveying degree, working in both the private and public sectors, and obtaining the two Texas professional surveying licenses. In 1999 he joined Loomis Austin (now Bowman Consulting) to start up the Surveying Department and was able to put together a versatile, talented, successful team of surveyors.

Bill accepted the offer by Texas Land Commissioner Jerry Patterson to be his Director of Surveying and Chief Surveyor at the Texas General Land Office in 2006 where he served until 2015. Bill returned to Bowman Consulting in August 2015 as a Senior Survey Project Manager.

On June 1, 2016, Bill started a private surveying practice to call on his vast experience in various types of surveying services and focus on complex boundary surveys, land title issues, gradient boundary surveys, coastal boundary surveys, riparian and littoral boundary issues, and “official” surveys for the Texas General Land Office.
