What Hampton, Lenzini and Renwick, Inc. (HLR) does

Hampton, Lenzini and Renwick, Inc. (HLR) is an employee-owned Illinois civil engineering firm founded in 1965 and headquartered in Elgin, Illinois. The firm delivers professional engineering services across civil and transportation engineering, structural engineering, land surveying, environmental services, construction engineering, traffic engineering, water/wastewater design, GIS services, land acquisition, building inspection, and energy services. HLR operates from five Illinois offices (Elgin HQ, Elgin secondary, Crystal Lake, Springfield, Mt. Carmel) and serves municipal governments, counties, school districts, park districts, and energy companies (Nicor Gas, North Shore Gas). Noteworthy technical capabilities include IDOT prequalification across 30+ engineering categories, drone-based surveying, 3D terrestrial laser scanning using RIEGL technology, and a first-of-its-kind ArcGIS-based public engagement and management platform deployed for the Elk Grove Business Park drainage program.

The firm generates revenue through professional services delivered on a project basis and through on-call consulting contracts with public-sector clients, primarily via competitive bidding and qualifications-based selection. HLR functions as an extension of client staff, evidenced by long-term relationships such as the City of Elgin partnership dating to 1977 and School District U-46 collaborations. The firm is in its fourth generation of employee ownership under President/CEO ReJena Lyon (since 2018), with Erica Spolar as Executive Vice President. HLR has been consistently recognized at industry level — including #1 ranking in PSMJ's 2025 AEC Employer of Choice and ISPE 2024 Best Places to Work — reflecting strong culture as a recruiting and retention asset in Illinois. Geographic scope is Illinois and broader Midwest; the firm has no disclosed parent company, no external funding rounds, and reports no acquisitions beyond the 2015 tuck-in of Lamac Engineering.
