[1] Upon returning to the U.S., Seator earned a BFA at the Massachusetts College of Art, Boston in 1984, and a MFA from SUNY Purchase in 1989.

[1] In his full-scale architectural reconstructions, the artist addressed the delicate balance of place, power and position.

[1] In an interview with the architectural historian, Anthony Vidler, Seator stated that a primary influence was the work of Gordon Matta Clark.

[4] The art historian Adam Weinberg has written that Seator's sculptural work had "a dramatic kinesthetic effect which may bring on vertigo.

"[5] Seator also produced sculptural procedure-based process artworks, such as the sweep-action piece, Untitled Auditorium Installation (1993) at MoMA PS1 in Queens, NY,[6] as well as the transformation of a townhouse he owned in the historical neighborhood of Vinegar Hill, Brooklyn into a work of installation art.

[3][7] Seator's first solo exhibition was in New York, followed by major installations in Warsaw, Vienna, San Francisco, London and Basel.

[8] In 2000-2001 his work was featured in a two-person exhibition, The Architectural Unconscious: James Casebere and Glen Seator, at the Addison Gallery of American Art at Phillips Academy in Andover, Massachusetts.

Seator's large-scale process-oriented exhibition at PS1 Museum in Long Island City, New York, extrapolated on his studio-based project Interrupted Sweeping (1991-1995) by enacting a long-term procedural action in which he used sweeping compound to clean the floor of the auditorium gallery nightly.

Installation at the National Gallery of Contemporary Art (Zaçheta), in Warsaw, Poland,[11] Seator meticulously covered the ornate Neo-Renaissance-style salon walls with horizontal strips of masking tape, creating "an etherial yet overwhelming image of itself."

[4] Art critic David Joselit wrote that the artwork enabled spectators to "carefully scrutinize" reality.

[4][14][15] Seator recreated every micro-detail of the outside street, including sidewalk cracks with bits of grass, chipped red curb paint, and graffiti on a telephone pole.

Commissioned by the Gagosian Gallery, Beverly Hills, CA, in 1999, was an exact replica of a check-cashing store located in a Latino neighborhood on Sunset Boulevard.

[7] In December 2002, Seator died in an accidental fall from his roof while repairing the chimney of his three-story townhouse located at 12 Duffield Street in Brooklyn, New York.
