Founders Ralph H. Cushing (standing) and Everett O. Terrell review designs circa 1965.

Welcome to Cushing, Terrell, and Associates — or as we like to call it, CTA Architects Engineers.

Founded in Billings, Montana in 1938, CTA’s focus from the outset was simplicity. As early adopters of integrated architectural and engineering services, we realize this goal in our culture of collaboration and trust. Innovation, we believe, thrives on working shoulder-to-shoulder toward elegant, efficient design solutions.

Since our humble beginnings, we have evolved to provide a variety of design services across industries and geographies, all the while upholding the pioneering spirit that inspired our first leaders. We proudly channel the simple, elegant beauty of Montana and embody the Mountain West region’s warmth in all of our design inspirations and client relationships.

We place a high value on the success of our clients, and let client care lead our work from start to forever.
