DLZ engineers, architects, and technical staff often live in the communities we serve. We work on the roads our kids travel to school, the water systems our neighbors rely on, the public buildings where they gather. That personal connection is strong — and it shows in the work we deliver, wherever we are.
DLZ NAMED AMONG
FASTEST-GROWING COMPANIES
From engineering and architecture to surveying and construction services, DLZ brings a rare depth and breadth of expertise to every client relationship. Our integrated, in-house teams collaborate across disciplines from day one — so you spend less time coordinating and more time moving forward. Whatever your project requires, the right people know each other and have collaborated for decades.
DLZ is built to scale with your needs. Whether your project calls for a focused team or a full multidisciplinary effort, we right-size our involvement to match your need, so you never sacrifice depth, quality, or responsiveness. Our industry expertise and thought leadership builds confidence, clarity, and maximum impact for communities and companies. Large or small, these partnerships build trust.
There is a reason clients come back to DLZ time and time again. Confidence is built on trust, responsiveness, and simply getting the job done right. This is the standard we’ve held ourselves to from the very start. Many clients start modestly, then increase our involvement as they grow. We stay accountable from the first meeting to the final deliverable. It’s the foundation for lasting partnerships.
DLZ’s roots stretch back more than 100 years, with several of our divisions providing professional services since 1916. What began as a small firm has grown into one of the nation’s top engineering, architecture and consulting practices — ranked among Engineering News-Record’s Top 500 Design Firms in the United States and 13th largest in the Midwest.
As a family and minority-owned business and graduate of the Federal 8(a) Business Development Program, DLZ’s growth is an American success story built on integrity, reinvestment, and an unwavering focus on client relationships. From six employees to more than 980 professionals across 33 US offices, the mission has never changed: deliver exceptional work, earn lasting trust, and leave every community better than we found it.
