With roots dating to 1964, OZ is named for two founders Tom Obermeier and Alan Zeigel, who believed that collaboration sparks creativity.

Today, we are comprised of 170 architects, interior designers, brand strategists, and support staff. The firm works in multiple practice areas that include cultural projects, such as libraries and museums, municipal and education facilities, urban living, workplace and hospitality projects. We have a large interior design group that works across practice areas and has extensive experience as well. Our diversity of expertise in multiple project types allows us to harness broad perspectives and share knowledge across our practice areas to drive innovative and sustainable design solutions.

We value a pioneering spirit, an attitude of openness, collaboration, stewardship of our communities, and the continuum of our practice which is now more than half-a-century old.

From our studio in the vibrant RiNo Arts District of Denver, we work across the nation and continents from Africa to Antarctica.
