Descriptiontext

Fehr Graham is a civil engineering and environmental consulting firm founded in 1973 in Freeport, Illinois, by Al Fehr and Joe Graham. The firm provides infrastructure and environmental services — including water and wastewater engineering, municipal engineering, transportation design, structural engineering, and brownfield redevelopment — to municipalities, developers, and select private-sector clients across the Midwest. It operates from 12 offices across Illinois, Iowa, and Wisconsin with approximately 260 employees, and senior leadership includes President Kyle Saunders and CFO Todd Shankland.

A distinguishing element of the firm's offering is its Funding Solutions practice, which navigates roughly 40–50 public and private funding-program databases at any given time and has reportedly secured more than $200 million in capital on behalf of clients. The practice combines traditional engineering consulting with grant and loan procurement assistance, shortening capital-project timelines for municipal clients that typically lack in-house grant-writing capacity. Services are delivered under project-based consulting contracts, generally awarded through municipal procurement processes or developer RFPs.

Fehr Graham has been recognized on Engineering News-Record's Top 500 Design Firms list for five consecutive years, ranking No. 452 in the most recent publication, and was named to the Zweig Group 2025 Hot Firm list. The firm is privately held and operates with backing from Trilon Group, a private equity platform focused on engineering and infrastructure businesses. The combination of regulated technical services, multi-state distribution, and embedded funding-procurement capability defines its operating model.
