Our Story
In 1938, Ralph Cushing and Everett Terrell formed one of the nation’s first integrated architecture and engineering firms, an alliance rarely seen back then. The success of this model has allowed CTA to expand to 15 offices across the U.S., garnering both national and international acclaims and has enabled our firm to attract the highest caliber of talented, passionate professionals.
CTA is recognized by clients, peers and industry professionals. Our projects have earned recognition and awards from the U.S. Environmental Protection Agency, the National Trust for Historic Preservation, the State of Montana, the American Institute of Architects, World Architecture News and Engineering News Record. In 2012, Architectural Record named CTA as one of the top 250 Architectural firms in the United States.
We continue to push the boundaries of design and creativity to Pioneer Environments.
