What Stolfus & Associates does

Stolfus & Associates, Inc. is a privately held Colorado-based transportation engineering consultancy founded in 2003 by Elizabeth Stolfus, PE, FACEC, who continues to serve as President and CEO. The firm provides four core service areas: Traffic Safety, Systems, Management & Operations; Transportation Infrastructure & Planning; Community Engagement; and Program Management & Advisory. It serves Colorado government clients including the Colorado Department of Transportation (CDOT) across all five regions and municipalities such as Aurora, Thornton, Denver (DOTI), Avon, Eagle, and Minturn, with the firm reporting it has served over 850 communities cumulatively since founding.

The firm's technical work is delivered using industry-standard transportation engineering and design software, including VISSIM for traffic simulation, Synchro for traffic signal analysis, OpenRoads Designer (ORD) for geometric modeling, ArcGIS for spatial analysis, and Python and AutoCAD. Team certifications include PE, PTOE, RSP, FACEC, ENV SP, and Bentley Accredited Road Modeler. Notable technical contributions include a compact modified single-lane roundabout design at the US 6 & Post Boulevard intersection (delivered $1.1M under construction budget, ACEC-Colorado Merit Award 2025) and the statewide Colorado Strategic Highway Safety Plan 2025 developed in partnership with VHB.

The firm operates a project-based professional services revenue model, acquiring work through competitive procurement including RFPs, mini-RFPs, and on-call contract task orders with government entities. The firm is bootstrapped with no disclosed external funding, maintains an estimated 17-person team headquartered in Greenwood Village, Colorado, and is wholly concentrated on Colorado-based public-sector transportation projects. Additional value-add services include grant application support (e.g., RAISE Grant, TAP DOLA, Revitalizing Main Street) and multimodal corridor design for pedestrian, bicycle, vehicle, and freight users.
