The firm was founded in February 2000 by Michael and Anne Killeen. In 2005, the team relocated to 3015 Salena Street, an 1886 factory building originally constructed by the Lecoutour Bros Stair Manufacturing Co. This building, now known as the Killeen Building, was transformed over a decade from a deteriorating structure into a vibrant, multi-tenant space housing photographers, attorneys, web developers, artists, and architects. The renovation, completed during the recession, was recognized with the "Most Enhanced" Landmarks Award by the Landmarks Association of St. Louis, reflecting the firm’s dedication to preservation and innovation.

The firm operates from 3015 Salena Street in the historic Benton Park neighborhood of St. Louis, a location that reflects its deep roots in the city’s architectural heritage. The building serves as both a workspace and a testament to the firm’s expertise in adaptive reuse and historic renovation.

Killeen Studio Architects maintains a 5.00 rating based on customer reviews, reflecting consistent client satisfaction with design quality, budget adherence, and service. The firm is recognized for its hands-on approach, collaborative process, and ability to deliver distinctive, functional spaces across residential and commercial sectors.
