What StudioGC does

StudioGC is a Chicago-based architecture and interior design firm founded in 1992 by Michael Gilfillan and Patrick Callahan with the mission to create excellent public facilities. The firm provides professional design services for both public and private sector clients, with a primary focus on community-oriented facilities including public libraries, K-12 educational institutions, parks and recreation centers, and municipal buildings such as police stations, fire stations, and village halls. Secondary verticals include corporate workplaces, healthcare facilities, and financial institutions. The firm operates from its Chicago headquarters at 223 W. Jackson Blvd., Suite 1200, with a secondary office in South Haven, Michigan, and has completed projects across Illinois, Wisconsin, and Michigan.

The firm's service portfolio spans the full project lifecycle, including architecture design, interior design, integrated design-build project delivery, planning and programming, cost estimating, and facility assessment services. StudioGC employs Building Information Modeling (BIM) software for design visualization and cost estimation, supplemented by a proprietary methodology called 'Spatial Agility Analysis™' that focuses on the evolving necessities and responsibilities of an environment to imagine enduring spaces for client investments. Notable project deliveries include the 54,000 sq. ft. Geneva Public Library District (completed May 2020), the 51,000 sq. ft. Don Preston Recreation Center expansion for Midlothian Park District, the 32,000 sq. ft. $7.5M Village of Milan combined police/village hall, the 7,160 sq. ft. Children's Dialysis Center, and the Mt. Prospect Park District multi-sport conversion (3,560 sq. ft., completed May 2025). The firm has received 12+ industry awards including American School & University Outstanding Design, Learning by Design Outstanding Project, and Chicago Building Congress Merit Award.

StudioGC generates revenue entirely through project-based, quote-driven professional services engagements secured via direct client relationships. The go-to-market model is relationship-driven sales targeting government agencies, school districts, park districts, municipalities, and select private-sector clients, with a vertical segmentation approach across five primary segments (Public Libraries, Education, Recreation, Municipal, and Workplace/Healthcare). The firm is independently owned with no external institutional investment, currently operates with 101-250 employees, and is led by seven principals including the two original founders, with active job openings indicating ongoing hiring.
