Serving our communities for over 35 years…
Heneghan and Associates, P.C. (HA) was founded in 1986, as a multi-disciplined civil engineering and surveying firm. We provide professional services to public and private sector clients. Our team of highly respected, educated, and experienced personnel has grown to a staff of more than 30 employees with offices in Mt. Vernon, Columbia and Jerseyville, Illinois and Arnold, Missouri.
We select our personnel for their technical abilities and willingness to participate in the collaborative process — necessary for successful project outcomes. Teamwork is a strategic commitment within HA. The firm utilizes partnering philosophies and creative teaming to optimize its diverse skills and develop strategic alliances with its clients.
Experience is more than just a term of value at Heneghan; it’s leadership and knowledge. We feature 13 engineers with a combined 300+ years of experience; and three surveyors with more than 70+ years of combined experience. That leadership team is supported by more than 14 CAD technicians, surveying technicians and administrative support staff. We boast a team that can easily meet the schedule, the budget, and the goals of your project.
In June 2013, HA began a new era by completing an internal ownership transition from founder and majority stockholder Dean Heneghan, to its current ownership of seven stockholders; Ronnie Paul, Curt Westrich, Seth Elliott, Josh Stumpe, Brandon Egelhoff, Adam Lott, and Lindsey Bowlin.
The future is bright at Heneghan and its clients will benefit from their creative design and well managed team. HA’s professional services feature transportation engineering, land planning/development (residential, commercial, industrial, institutional, recreational), environmental engineering (water, wastewater, storm water), surveying, and funding assistance.
