To better represent our growth and diversity as a whole, we changed our name to Warrenstreet Architects, Inc., and in 2008, modified our business structure to that of an employee-owned cooperative. An ever-growing trend in today's business structure models, cooperatives like ours embrace the underlying culture and commitment of seeing one another and our firm succeed and is why our clients and their projects receive more value.
