Life at OPN

Our Culture
“Collaboration, kindness, and passion make our studios unique.”
Erica Steapp Interior Designer
“Our studios are unique because of collaboration. Someone may have a good idea, but it's only with many that it can be brought to life.”
Alexander Michl Architectural Intern

Building a better world

At the center of our core values is our shared commitment to community involvement. OPN is invested in the well-being of its communities and often donates time, talent, and money to organizations in need. As a firm, we regularly undertake pro-bono projects; office-wide, we annually support Habitat for Humanity, Canstruction, and United Way. Our designers serve on boards and committees for national- and state-level professional organizations and have been recognized for their advocacy in architectural and civic life. In the aftermath of the devastating floods of 2008, OPN offered its services to civic and corporate entities to recover and revive the affected areas, including Cedar Rapids, Iowa City, and Des Moines, Iowa.
