Callison was a global architecture firm based in Seattle, Washington. Founded in 1975 by Tony Callison, the company expanded to employ approximately 900 professionals worldwide prior to its acquisition by Arcadis NV in 2014. In October 2015, Callison combined with Arcadis's subsidiary RTKL Associates, resulting in the formation of CallisonRTKL, with headquarters located in Baltimore, Maryland.
The firm’s expertise encompassed planning and design services for retail, hospitality, mixed-use developments, workplace environments, corporate offices, and healthcare facilities on an international scale.
Corporate
Callison was founded in Seattle in 1975 and eventually grew to a workforce exceeding 900 employees. Its global presence included offices in cities such as Seattle, Los Angeles, Mexico City, Dallas, Scottsdale, New York City, London, and Dubai, along with major urban centers in China including Beijing, Shanghai, and Guangzhou.
In August 2014, the Amsterdam-headquartered design and engineering firm Arcadis NV acquired Callison. Post-acquisition, Arcadis promoted Callison alongside its Baltimore-based RTKL division under the unified brand "CallisonRTKL." The official consolidation took place in October 2015, creating a company that had generated $402.4 million in architectural and engineering revenue the year before, ranking fifth nationally according to Architectural Record.
Throughout its history, Callison received numerous accolades recognizing its achievements in design excellence, architectural innovation, and sustainable design leadership.
