HILGARTWILSON was founded by Ron Hilgart and Darrell Wilson with the promise to provide exemplary consulting in civil engineering, land use planning, land surveying, environmental services, and construction management. Formed in 2009, despite the economic uncertainty of the Great Recession, Ron and Darrell kept an unwavering commitment to their clients. They have grown the company into a leading Arizona firm by providing innovative solutions and unmatched client service.

We approach each project as a partnership with our client. As their advocates, project design, timelines, and resolutions are executed based on their best interests. Our work speaks for itself. HILGARTWILSON is trusted by our clientele to work on some of the largest, most prestigious master-planned community, industrial, commercial, educational, mixed-use, and public works projects throughout the state.

The ‘partnership’ philosophy creates a work culture that heavily focuses on individual excellence within a team environment. HILGARTWILSON provides numerous personal growth opportunities for our staff, which includes training by both internal and external industry experts. As civil engineers, our commitment to our community doesn’t end with helping shape and build it.
