Cohos Evamy was founded as an architecture and engineering studio in
Calgary, Alberta, Canada in 1960, and quickly evolved into an interdisciplinary model under the leadership of Martin Cohos, FRAIC, Michael Evamy, FAIC and Paul Poffenroth, P.Eng. The Cohos Evamy Partners opened the Edmonton office in the 1980s. In 2003, Cohos Evamy opened a
Toronto, Ontario studio. Together, the three studios in Calgary, Edmonton and Toronto serve Canada from the West coast to the East coast. In 2010, Cohos Evamy merged with Vancouver-based architectural firm HBBH, among others, and was renamed DIALOG. ==Areas of practice==
