HGA is an interdisciplinary design firm committed to making a positive, lasting impact for our clients and communities through research-based, holistic solutions.

We believe that great design requires a sense of curiosity—forming deep insight into our clients, their contexts, and the human condition. As a collective of design professionals working together across diverse backgrounds and disciplines, we seek to understand and optimize all aspects of each unique environment: human experience, cultural significance, technical rigor, systems performance, and resiliency.

With over 800 architects, engineers, interior designers, planners, researchers, and strategists, HGA has built a network of expertise and a culture of knowledge-sharing to address the increasing complexities faced by our clients. With a history of working as an interdisciplinary practice, we have developed a truly integrated approach that yields inventive, efficient, and humane responses to the profound challenges of our time.

Founded in Minneapolis in 1953, HGA now has 11 locations coast to coast: Boston, MA; Washington, DC; Alexandria, VA; Madison and Milwaukee, WI; Minneapolis and Rochester, MN; and Los Angeles, Sacramento, San Francisco, and San Jose, CA. Our practice spans multiple markets, including corporate, cultural, education, local and federal government, healthcare, and science and technology.
