About Us
Simpson Coulter Studio is a team of curious and collaborative professionals committed to creating spaces that make a meaningful difference in the communities we serve. Since 1967, we’ve shaped environments across the Southwest region — from schools to convention centers. Every project is fueled by a dedication to listening first, understanding deeply, and designing with intention. We don’t take ourselves too seriously, but when it comes to our work, we put our clients and communities at the center of every decision.
