ST. LOUIS, MO — Burns & McDonnell has named Adam Matthiesen as General Manager for the firm’s Midwest Region, which includes more than 500 employee-owners across offices in St. Louis, Missouri; Akron and Columbus, Ohio; and O’Fallon, Illinois. Matthiesen is succeeding Senior Vice President Breck Washam, who plans to retire in early 2027.
As General Manager, Matthiesen will oversee the region, which serves clients across the Central and Upper Midwest while delivering integrated engineering, construction, and consulting solutions for critical infrastructure projects in energy, water, power, environmental, industrial, manufacturing, and other sectors.
“Adam’s leadership, operational experience, and commitment to our employee-owner culture make him exceptionally well positioned to lead the Midwest Region into its next chapter,” said Jerry Fan, Executive Vice President and General Manager of the Americas North Region. “As he steps into this role, we are confident he will continue advancing the culture, client relationships, and success that Breck helped build over nearly two decades of leadership.”
Matthiesen has more than 15 years of experience leading engineering and construction projects across the energy and infrastructure sectors. He joined Burns & McDonnell in 2009 and has held a variety of leadership roles across the company. Most recently, he served as Operations Director for the Midwest Region and was promoted to Vice President in 2025.
Prior to joining the Midwest Region in 2021 as Leader for the Transmission & Distribution Group, Matthiesen spent more than a decade in the Houston, Texas, office, managing multidisciplinary engineering and construction teams on projects nationwide.
