Moed de Armas and Shannon

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,[1] Gotham Center,[2] the rejuvenation of the GM Building Plaza,[3] 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 [4] in Toronto.

The firm has a particular focus on facade replacements, public spaces and lobby renovations.[5]
