Forensic engineering was still an emerging discipline in 1924 when veteran civil engineer Walter G. Haag founded his consulting company in Dallas, Texas, to appraise or value properties for a sale of the business.  As his reputation grew, so did the forensic engineering field, and Mr. Haag began valuing properties after losses. By the time Mr. Haag retired from the company shortly before his death in 1956, forensic engineering was a full-fledged profession and Haag Engineering was ready to expand from North Texas to the world.

The man who set that expansion in motion was Charles W. Parish. A chemical engineer who came of age serving with the Army Air Force in the Pacific in World War II, Parish had come to work for Walter Haag in 1946. Taking over for his mentor 10 years later, he soon opened the company’s first satellite office, in Houston — just in time for Hurricane Carla.

In 1982, John Stewart, P.E., took over as president and has been a Haag engineer for 50 years (and still going). Justin Kestner, P.E., became Haag’s president in 2014. Haag has steadily grown its national presence, expanding from just our original location in Dallas to more than 23+ locations nationwide today.

For over 98 years, Haag’s purpose has been to find and communicate the facts. We are known for scientific rigor, precision, and clarity. Haag’s engineering and consulting professionals have become a vital resource for clients in the legal, insurance, EAC, manufacturing, and other sectors.
