Wank Adams Slavin Associates was an American architecture firm that grew out of Reed & Stem (1889-1923) and Fellheimer & Wagner (1923-1961). Both early firms were known for their work with train station design; Reed & Stem won the commission for Grand Central Terminal, and Fellheimer & Wagner specialized in Art Deco and Beaux-Arts train stations. However, Fellheimer & Wagner also expanded into financial institutions, educational complexes, housing facilities, and laboratories. This would continue to expand under the leadership of Roland Wank with Wank Adams Slavin Associates. Relationships between firm partners and government institutions were also an important source for commissions. The firm has been active as WASA Studio since 2005.
