Firm History

DePauli Engineering & Surveying, LLC. of Gallup, New Mexico was established on January 1, 2000 with the  start of the new millennium, when the owners of Sterling and Mataya, Engineers and Surveyors, Donald Sterling and William Mataya sold the firm to Marc DePaui. The story of this small town company started out as a small firm  known as Allgood Engineer, created by Richard Allgood in 1967. Later on civil engineer Donald Sterling joined the company in 1968.  Bill Mataya, a surveyor for the City of Gallup, was partners with Joe Martinez in the mid 1960's.  After splitting, he joined with Allgood and Sterling, and the company changed to Allgood, Sterling and Mataya.  With the retiring of Allgood, the company changed the name to Sterling and Mataya, Engineers and Surveyors in 1981.  The company slowly grew in size, adding more engineers and surveyors. With the start of the new millennnium, Sterling and Mataya sold the company to Marc DePauli, establishing the company known today as DePauli Engineering & Surveying, LLC.
