Creating Tomorrow, Together in Kansas City

Partnering to create lasting change, uniting people and transforming the places we call home.

Kansas City is building momentum with growth in infrastructure development, sports facilities, and cultural institutions. Communities are working to modernize aging systems, adapt to evolving regulations, and meet rising demands for power, water, wastewater, telecommunications, and transportation networks. While funding and workforce availability present challenges, they also create opportunities for smarter, more efficient approaches to both new construction and maintenance projects.

As a 100% employee-owned professional services firm, we bring a culture of accountability and collaboration to our projects. We specialize in architecture, engineering, environmental and construction services — delivering projects that support the communities where we live and work. We provide a range of local technical expertise and project management to address infrastructure challenges. Backed by a strong network and a focused approach, we bring together the right people and experience to support diverse project needs and help communities move forward.
