About Us

Nathan Steinhauer

Nate is beginning his architectural career at DM+A. Graduating with his Bachelor of Architecture (2020) and pursuing a Master of Architecture from Pennsylvania State University, he is thrilled to relocate to the “Queen City.” Born and raised in Pittsburgh, PA, his love of architecture stemmed from Frank Lloyd Wright’s Fallingwater, which was just a short drive away. Nate credits his former summer internship of three years at WTW Architects to his knowledge of the professional architectural field. Nate’s love of biking propelled his latter years of college to focus on urban scaled transportation issues. He hopes to use that knowledge to understand the greater context of neighborhood layouts.
