Hammel, Green and Abrahamson

From Wikipedia, the free encyclopedia

Hammel, Green and Abrahamson (HGA) is an architecture, engineering, and planning firm that originated in Minnesota. It was founded in 1953 by Minnesotans Dick Hammel and Curt Green (Bruce Abrahamson joined shortly thereafter).

All three of HGA's founders were schooled in the Bauhaus tradition, which stressed a collaborative and inter-disciplinary approach to Modernism. They began their work designing K-12 school buildings. The firm later expanded into other areas, such as healthcare, corporate environments and higher education. They are currently one of the largest firms in Minnesota.

HGA has expanded into twelve national offices: Minneapolis and Rochester, Minnesota; Los Angeles, Sacramento, San Diego, San Jose and San Francisco in California; Milwaukee and Madison in Wisconsin; Boston; Alexandria, Virginia; and Washington, D.C.[1]

In October 2018, HGA announced its acquisition of Wilson Architects, a Boston-based firm specializing in science and technology facilities for higher education and corporate clients.[2]
