Jones Engineers started as a small business operated from the home of its founder, Harry P. "Pat" Jones in January, 1964. During the next few decades the operation grew from a one man business to one of the major civil engineering and land surveying firms in the Pacific Northwest.

During the first years of operation the expansion of the company could be described as "explosive".  The firm grew during the 1960's and 70's to one of the top design firms in the United States (Engineering News Record Magazine's ENR Top 500). In the early 80's the firm designed and developed a new office park on Northup Way in Bellevue, Washington and consolidated the corporate offices there.  In 1990 Pat Jones moved the corporate office to Bellingham, Washington and since that time Jones Engineers has enjoyed a positive role in the growth and development of the region.

In 1988, Darcy Jones opened the San Diego office of Jones Engineers, and in 2004 purchased the Bellingham business.  Since that time, Jones Engineers continues to be actively engaged in the land development and engineering communities of Western Washington and Southern California.
