About Haag

Charles Wayne Parish and Walter G. Haag, founders of Haag Engineering Co.

In the summer of 1924, Walter G. Haag, with 25 years of civil engineering experience and an entrepreneurial spirit, founded his own failure and damage consulting company in Dallas, Texas. In the beginning, Haag valued properties after losses. As his reputation grew, clients also requested he evaluate the cause of loss. Mr. C. Wayne Parish, a WWII Air Force engineer who served in the Pacific theatre, joined Mr. Haag in 1946. Mr. Parish took over leadership of Haag Engineering following Mr. Haag’s retirement. Mr. Parish expanded the company into a nationwide presence.   

Today, Haag is a multi-faceted forensic engineering and consulting company.

Our History

Building on a tradition of excellence since 1924

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 took over as president and has been a Haag engineer for 50 years (and still going). Justin Kestner became Haag's president in 2014. The growth of the company’s office network has been steady — expanding from Dallas to more than 18 locations nationwide. 

For 95 years, Haag's purpose has been to find and communicate the facts. With their reputation for scientific rigor, precision, and for the clarity with which they impart their insights, Haag engineering and consulting professionals have become a vital resource for clients in the legal and insurance fields, architecture and construction, manufacturing, and many other industries.
