Carl A. Worthington AIA, ASLA

Since 1962, Carl A. Worthington & Associates has focused on Architecture, Urban Design and Master Planning for significant work, not measured by size, but by relevance to how a project’s development impacts its investors, the community, the built-environment, and setting. Projects such as the Denver Technological Center, Westminster Promenade, Downtown Pearl Street Mall in Colorado, and the Kigali City Master Planning in Rwanda have been highlights in his prominent career. Working around the world in over 14 countries, he has been creating complex themed mixed-use environments that become the “heart” of the setting they find themselves in, whether an urban center or a new community. Since 2002, Carl has acted as Director of Urban Design for OZ Architecture.
