The combination of both companies provides a new platform to tackle challenges within the AEC industry and serve the ever-changing needs of clients.

HUNT VALLEY, Md. and VIRGINIA BEACH, Va., May 21, 2025 /PRNewswire/ -- Johnson, Mirmiran & Thompson (JMT), an engineering, architecture, technology, and related consulting services company, and Clark Nexsen, an architecture and engineering firm, announced today that they are combining forces in a transformative merger that will create an employee-owned industry leader in planning, design, architecture, engineering, and construction for clients in the United States and around the world.

As part of this merger, Clark Nexsen staff become part of JMT's 100-percent employee-owned structure—one of the largest ESOPs in the AEC industry—reinforcing the shared commitment to long-term growth, innovation, and client success. This alignment is further strengthened by the cultural fit between the two firms. Both JMT and Clark Nexsen are perennially ranked among the Top 500 Design Firms by Engineering News-Record and share a deep-rooted belief in fostering strong workplace cultures and actively engaging in the communities where their employees live and work.

"A shared corporate culture will be the foundation of this union's success," said JMT President Mike Blair, PE. "I'm excited about expanding JMT's capabilities and developing new opportunities for everyone to succeed. I believe this will be a transformative next step for both firms."

The merger will create a firm of more than 2,750 employees and strengthen each other's architecture and engineering practices, particularly in the Mid-Atlantic and Southeast United States. Clark Nexsen will leverage its expertise in architecture and facilities engineering to enhance JMT's capabilities. Its transportation team will also reinforce JMT's presence in that sector. Together, the combined firms will become a powerhouse in the education and federal market sectors, which JMT and Clark Nexsen both serve.

"Combining with JMT is transformative for all of us," said Clark Nexsen President Terri Hall, PE, LEED AP. "We will continue to build on more than a century of achievements, add new geographies and areas of expertise, and provide our employees with many new avenues for professional growth. This is truly an exciting time."
