WASA Studio is one of the oldest American architectural and engineering firms. Founded in 1891 as Reed and Stem in St. Paul, Minnesota as a partnership between Charles A. Reed (1858-1911) and Allen H. Stem (1856-1931), the successful partnership captured a wide range of commissions. The firm was reformed as Wank Adams Slavin Associates in 1961, and adopted the name WASA Studio in 2004.
