HOK, the global architecture firm known for stadiums and large-scale entertainment venues, has acquired Detroit-based Rossetti, pulling the city’s long-running sports-venue specialist into its Sports + Recreation + Entertainment practice. The deal keeps Rossetti’s design team planted in Detroit while handing the studio access to HOK’s international platform and technical muscle. For a city actively rebuilding its sports and entertainment corridor, the move ties local know-how to a much larger national operation without shipping the talent out of town.
In a press release via HOK, the firms said the combined practice will operate as HOK + ROSSETTI during an integration period, with Matt Rossetti joining HOK as a director and shareholder while continuing to lead the Detroit studio. The announcement presents the acquisition as a strategic add-on to HOK’s existing sports portfolio and a way to give Rossetti’s staff a wider range of projects to work on. “This is the right partnership at the right time,” Matt Rossetti said in a statement via ROSSETTI.
Deal Details and Leadership
Industry reporting indicates that all of Rossetti’s staff will join HOK, and Sports Business Journal reported that roughly 87 employees are expected to transfer. The combined sports practice will be led by directors Nate Appleman, Shannon Bartch, Amy Chase, John Rhodes, Rashed Singaby and Matt Rossetti. That leadership group is tasked with folding the Detroit studio into HOK’s global operations while chasing larger stadium and arena commissions. Observers say the structure effectively gives HOK an instant delivery team in the Upper Midwest.
Rossetti’s Detroit Roots and Projects
Rossetti has been a Detroit fixture for nearly six decades and points to a portfolio of high-profile stadium work, including Ford Field, the USTA Billie Jean King National Tennis Center and the Cosm Detroit project, according to ROSSETTI. The firm also brings deep experience in training facilities, arenas and sports-anchored mixed-use districts, areas that HOK says will complement its existing strengths. That level of local expertise is likely to be a key selling point for Detroit developers and teams that want a national player without losing a hometown perspective.
What It Means for Detroit and the Industry
HOK said the acquisition establishes a home in Detroit and deepens its sports practice, giving local clients access to a broader pool of technical and design resources. The larger firm’s portfolio already includes major NFL and MLS renovation projects, and the combination is expected to make it easier for Detroit teams and developers to tap into national-scale delivery while holding onto local continuity. Leaders from both organizations say the deal positions the Detroit studio to compete for larger national and international commissions while remaining firmly rooted in the city.
Terms of the transaction were not disclosed, and local business outlets jumped on the story as it landed, with Crain's Detroit Business publishing an account of the deal. Company statements say integration will move ahead while Rossetti’s Detroit office continues to service its existing work, including the Cosm Detroit reimagining and the USTA Arthur Ashe program.
