DB Sterlin Acquires Wisconsin-Based M Squared Engineering

DB Sterlin Consultants, Inc. (“DB Sterlin”) is pleased to announce the acquisition of M Squared Engineering, LLC (“M2”), a Wisconsin-based civil engineering firm known for its strong commitment to integrity, technical excellence, and innovative solutions.

Founded in 2003, M2 has grown from a two-person startup to a team of over 20 professionals by consistently delivering high-quality results and creating long-term value for its clients. With specialties in water resources, transportation engineering, land development, site planning, construction engineering, and land surveying, M2 has built a trusted reputation across Wisconsin and Illinois, serving federal, state, and local agencies, as well as municipalities, developers, and private landowners.

M2’s growth has been driven by their staff’s passion for engineering and a dedication to client success with every project—qualities aligning with DB Sterlin’s own values. This acquisition marks a strategic step forward for both organizations, expanding DB Sterlin’s geographic footprint while strengthening its capabilities in complex water resources and transportation engineering. Together, we look forward to offering enhanced expertise, broader resources, and greater value to our clients.

Based in Chicago, DB Sterlin has established itself as an industry leader and a trusted advisor in the Illinois infrastructure industry, providing expertise in civil, structural, electrical, construction management, utilities engineering, and land surveying for over 28 years. DB Sterlin has built a reputation for adaptability, customer service, and professional excellence, delivering customized engineering and consulting solutions that produce measurable and lasting outcomes for clients including the Illinois Department of Transportation, Illinois Tollway, the City of Chicago, Cook County, the U.S. Army Corps of Engineers, the Department of Water Management, railroad clients, and both private and utilities.

Regine Sterlin Jeune, President of DB Sterlin, commented:

“This acquisition is a powerful step forward for us all, built on a foundation of shared values, a common vision, and mutual respect. By joining forces, we’re not just expanding our geographic footprint—we’re amplifying our collective strength, talent, and capabilities. Together, we are poised to drive new opportunities, innovation, and deliver great value for our clients.”

Minal Hahm, PE, CFM, Principal of M2, stated:

“Partnering with DB Sterlin means we can keep doing what we do best—delivering great engineering and solid project management—while gaining access to new tools, talent, and ideas that help us take on even bigger and more complex projects with confidence. If you think we’ve been great on our own, just wait until you see what we can do together with DB Sterlin. This partnership lets us keep delivering the quality you expect—now with even more horsepower behind every project."
