Our National Reach
From a basement office shared by our three founders in 1954, we have grown into 12 national offices with more than 1,000 employees. Multidisciplinary teams collaborate across the company to deliver local and sector-specific expertise backed by the resources of a national firm. Each of our 12 offices is home to people deeply embedded in their communities: attending the same community meetings as our clients, invested in the same neighborhoods, shaped by the same local context. That’s not incidental to the work we do. It’s central to it.
Local Pulse
Each HGA office is shaped by the community it calls home. Local Pulse is a series exploring the people, projects, and perspectives that define our work across the country — from the design challenges we navigate, to the teams driving them, to the conversations that keep us connected.

From coast to coast, we work together to make a positive, lasting impact for clients in healthcare, arts and culture, community, corporate, education, government, and energy markets.
The art of interdisciplinary design
Great design starts by understanding the people who use a space and place — and what truly matters to them. We believe the best design results from deep insight into the people and passions that animate each unique environment.
Arts + Culture
In our post-pandemic world, arts + cultural facilities are being reimagined as interactive destinations for community gathering, multidisciplinary performance, immersive exhibition, and technological experimentation. Inside and out, these buildings must reflect and inspire the communities they serve and be ready for what’s next.
Learn MoreCommunity + Live
Enduring design requires the willingness to understand the culture and personality of a community as context for the design objectives at hand. For more than six decades, we have been entrusted to work on some of the most important landmarks in our clients’ communities—revitalizing, restoring, expanding, and designing memorable spaces that become beloved icons.
Learn MoreWorkplace
A company’s brand, culture, and vision remain foundational to creating a successful and productive workplace. To help our clients navigate the ever-changing world we live in, we are committed to creating flexible, inspiring places where people can do their best work.
Learn MoreEnergy + Infrastruct
As engineering specialists within an interdisciplinary practice, we have a holistic understanding of the impact of our work; we are able to integrate our technical solutions with other important elements of a project, from the elements that are critical to quality of healthcare to higher education to corporate campus design.
Learn MoreEducation
We work with diverse campuses across the country – from top tier research universities to community colleges, private liberal arts institutions, and K-12 schools. Education is facing enormous challenges including decreased funding, systemic inequities, and declining demographics.
Learn MoreGovernment

Our teams have decades of experience designing and revitalizing government buildings including office buildings, libraries, ports of entry, transit and transportation hubs, and historically significant buildings.
