MdeAS Architects (em/dee/ay/es), formerly Moed de Armas & Shannon Architects, is a New York-based architecture firm known for modern design focusing on the quality of natural materials, intelligent programming, and the redefining of Class A buildings, interiors, and public spaces. Founded in 1991, the award-winning studio is led by principals Dan Shannon, Raúl de Armas and Mike Zaborski.

History

Partners Leon Moed and Raul de Armas founded the firm in 1991 after leaving their positions as senior partners at Skidmore, Owings & Merrill. Dan Shannon, an associate at SOM, joined Moed de Armas Architects at its founding. In 1997, he became a partner and the firm changed its name to Moed de Armas & Shannon. Mike Zaborski joined the firm in 1998 and became a partner in 2012. The firm officially changed its name to MdeAS Architects in October 2014. They have jointly completed 510 Madison Avenue, Gotham Center, the rejuvenation of the GM Building Plaza, and the redevelopments of 100 Park Avenue and 330 Madison Avenue. The firm also designed a glass spandrel system to replace the deteriorating marble façade of Canada's tallest building, First Canadian Place in Toronto.
