SPS+ Architects was established in 1960 by Wendell Rossman, a forward-thinking architect who set our firm's precedent of innovation through design. Rossman's experimental concrete forms of the '60s, such as St. Maria Goretti Church and Arizona State University's Manzanita Hall, are now local landmarks. Since that time, our firm has designed what continues to be the largest wood-frame structures in the world (including the NAU Skydome) and developed the Turntable Divisible Auditorium (featured in the Chandler Center for the Arts), a design solution which has become widespread internationally.
