KMA Architecture & Engineering was founded in 1973 by William Krommenhoek. Originally named Krommenhoek and Associates, its patron client was San Diego Federal Savings and Loan. The firm went on to design over 250 branch banks for San Diego Federal, later named Great American First Savings Bank.

In 1978 Jack McKeown became a partner, and the firm was renamed Krommenhoek McKeown and Associates. Over the next 12 years the firm expanded its portfolio to include work for commercial developers, hotels, office, multi-unit residential, specialized technical and industrial buildings, and military work. 

In 1990 the firm was renamed KMA Architecture & Engineering under the lead of Partners, Don Blair & Timothy Rubesh. In 2014, the firm's name was simplified to KMA Architecture and Don Blair became the sole Principal. Around this time, the office relocated to their current location at Liberty Station in Point Loma. 

The KMA approach to design has been evolving for over 49 years and can best be described as a “creative analytical” process founded on research leading to a comprehensive understanding of the constraints and opportunities impacting a specific architectural project. Within this framework multiple design solutions are developed and evaluated during the design process using a variety of design tools, both traditional and “high-tech.” The company continuously invests in its people, in the latest state-of-the-art design technologies, and in developing better methods with which to bring value to our clients’ projects.
