Who we are

At Mason & Hanger, “Building a More Secure World” is more than just a tagline. For almost 200 years and on thousands of projects across the United States and in 165 countries around the world, supporting the mission of the U.S. federal government has been our sole focus. With a full array of in-house multi-discipline professionals and a staff of more than 250, we specialize in the planning and design of secure, mission-driven facilities. These facilities include educational institutions, classrooms, training facilities, assembly halls, athletic facilities, secure buildings, data centers, command and control centers, communications facilities, headquarters facilities, embassies, SCIF spaces, and many others. 

Mason & Hanger’s secure facility design practice includes both new facilities and the renovation and upgrade of existing facilities and systems. Renovation of existing mission critical facilities is especially challenging because they must maintain full operation during construction. For these projects, we have developed extensive and detailed phasing plans requiring specific construction sequencing in order to maintain student health and safety during construction and commissioning. 

We recognize every client and project is unique, and we integrate our collective resources to offer a customized streamlined solution for every mission.
