Burns & McDonnell

At Burns & McDonnell, our engineers, construction professionals, architects, planners, technologists and scientists do more than plan, design and construct. With a mission unchanged since 1898 — make our clients successful — our more than 13,500 professionals partner with you on the toughest challenges, constantly working to make the world an amazing place. Each professional brings an ownership mentality to projects at our 100% employee-owned firm, which has safety performance among the top 5% of AEC firms. As dedicated owners, we work through challenges until they're resolved, meeting or exceeding our clients' goals. We apply this commitment to our communities, too. We live and work in the same cities you call home, so we share a passion to keep them strong and healthy. From fundraising events and community cleanups to educational outreach and mentorship — especially when it comes to sharing our passion for STEM — our professionals work to make our communities thrive.
