Nation’s fourth largest architecture and design firm expands into Boston, strengthening its East Coast presence

Global architecture and design firm Corgan has acquired Boston-based Dyer Brown in a move grounded in shared values and a commitment to design excellence—strengthening their collective impact. This addition reinforces Corgan’s presence in the Eastern United States—adding to its established New York and Washington D.C. offices while providing Dyer Brown’s clients and team access to broader expertise and national reach. Corgan, ranked as the fourth largest architecture and design firm in the US, has a large interiors and workplace practice serving global clients across financial services, consulting, technology and consumer brands. Dyer Brown, a 56-year-old firm, has a diverse interiors portfolio including hospitality, retail, building repositioning and healthcare with deep experience in workplace—all of which aligns with Corgan’s expertise.

“This partnership was driven by more than just strategy—it’s about cultural and creative alignment,” said Scott Ruch, CEO of Corgan. “Both firms share a belief in the power of design, a commitment to client relationships, and a people-first culture. We’re excited about what we’ll accomplish together.”

Corgan, an 87-year-old firm, has experienced significant organic growth and operates in 19 offices across the US, UK, Dublin and Singapore with more than 1,200 employees. Dyer Brown’s portfolio of work and nearly 30 employees, including the firm’s principals, as well as current office, will now operate as part of Corgan’s global practice.

“It is an exciting time to join Corgan,” said Brent Zeigler, Dyer Brown’s President and Principal. “From the start, it was clear that this was more than an acquisition—it was a values match. Corgan’s global platform will create new opportunities for our team and our clients, and we’re confident this move allows us to grow while continuing to do the work we love.”

Corgan services a variety of sectors and ranks as the #1 data center and #2 aviation architecture firm as well as an Interior Design Giant and American Society of Interior Designers Firm of the Year. Corgan and Dyer Brown share a legacy of design excellence and trusted client relationships, each with a strong portfolio and a high percentage of repeat client work — a testament to the quality and consistency they deliver both in the US and internationally.

“Similar to Corgan, Dyer Brown has a strong workplace interiors portfolio and by joining forces, we are amplifying our workplace practice—bringing together deep expertise in strategy, design, and delivery to create environments that elevate employee experience and reflect the evolving role of workplaces for organizations today,” said Lindsay Wilson, President, Principal and Interiors Sector Leader for Corgan. “We are thrilled to collaborate with a team that shares our passion for purposeful design and innovation, and we look forward to what we’ll build together—spaces that inspire people and drive organizational impact.”

Morrissey Goodale served as advisor to Corgan.
