At Heneghan Associates, we are a multi-disciplined civil engineering and surveying firm that has been serving our communities for over 38 years. We provide professional services to both public and private sector clients, and 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.

Our mission statement is to deliver valuable, professional services through a creative, practical, collaborative design process, resulting in an improved quality of life to the communities and stakeholders we serve. We believe in instilling a culture of trust and value as we improve the quality of life for all those living and working in the communities we serve, while providing opportunities for continued growth and success to our firm members.

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 our company. We utilize partnering philosophies and creative teaming to optimize our diverse skills and develop strategic alliances with our clients.

Experience is more than just a term of value at Heneghan Associates; 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 engineering 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, we began a new era by completing an internal ownership transition from founder and majority stockholder Dean Heneghan to our current ownership of seven stockholders: Curt Westrich, Ronnie Paul, Josh Stumpe, Seth Elliott, Brandon Egelhoff, Adam Lott, and Lindsey Bowlin. The future is bright at Heneghan Associates, and our clients will benefit from our creative design and well-managed team.
