Donald M. Sheridan first cut his teeth in silkscreen at age 18 (1968), printing political protest posters in San Francisco. He later moved to New York City and became engaged in fine art silkscreen printmaking in 1977, when he began working in the studio of Rupert Jasen Smith, Master Printer to Andy Warhol. He printed Warhol’s work for six years, and at intervals throughout subsequent years. Starting in 1982, he also worked with Larry B. Wright, printing editions by Robert Rauschenberg, Larry Poons, Larry Zox, Dan Christensen, and others.

In 1984, he established his own studio, Donald M. Sheridan Fine Arts, at 350 Manhattan Avenue in Williamsburg, Brooklyn. There, he published portfolios and editions by emerging and established contemporary artists, collaborating with those who sought to enlarge their repertoire by producing printed editions and unique monoprints. He continued to engage in contract printing until his final illness, which was attributed to solvent exposure over a long career.

In 1992, the studio moved to Manhattan for seven years, and then to Jersey City, NJ, where it housed two silkscreen presses—including one measuring 12' × 80", capable of producing very large works. In 2019, he moved the studio to the Garner Arts Center in Garnerville, NY.

From the mid-1990s until COVID-19 arrived in 2020, Donald taught silkscreen printing at the School of Visual Arts in Manhattan.
