In 1976, Heiss founded P.S.1 Contemporary Art Center (now
MoMA PS1), an institution dedicated to contemporary art housed in a Romanesque-revival school building in
Long Island City, Queens, New York. The museum opened in June 1976 with the inaugural "Rooms" exhibit, for which Heiss invited a great number of artists - many of whom experimented with such new forms as video, installation, and performance art - to install their work throughout the building.

Artist Richard Nonas later remarked that "Alanna is probably the most important single figure in that effluence of another kind of art-making or art-doing in New York in the seventies — not only the art itself but also the way the art existed in the city." Over the next three decades, P.S.1 became one of the most respected exhibition and performance spaces in New York, with such exhibitions as New York, New Wave (1981); Stalin's Choice: Soviet Socialist Realism, 1932–1956 (1993); Greater New York (2000 and 2005), and Arctic Hysteria (2008); Robert Grosvenor (1976);
Keith Sonnier (1983);
Alex Katz: Under the Stars, American Landscapes 1951–1995 (1998);
John Wesley: Paintings 1961–2000 (2000), and
Gino De Dominicis (2008). In 2000, the organization became affiliated with
The Museum of Modern Art, giving it greater financial stability, extending the reach of both institutions, and combining P.S.1's contemporary mission with MoMA's strength as one of the greatest collecting museums of modern art. The deal allowed MoMA, after a seven-year period, to take command of P.S.1's financial management and the appointment of its board members. In 2008, shortly after this seven-year period, Heiss left P.S.1 to create AIR, Art International Radio. ==AIR, Art International Radio==
