Gretchen has taught at the graduate and undergraduate levels for the better part of two decades. She has served on the faculties at Georgetown University, University of Utah, MIT, Knox College, University of Missouri-Columbia, Barnard College's Center for Research on Women, Kenyon Review Writers Workshop, and elsewhere, and is frequently invited as a visiting writer/artist/scholar. With writing at the core of her practice, she has taught in departments of English, Creative Writing, Comparative Media Studies, Art History, Museum Studies, Environmental Humanities, among others. Her classes often go beyond the classroom. Her class field trips have ranged from the Isabella Stewart Gardner Museum and other museums and studios in Boston, to the National Gallery of Art and National Press Club in Washington, DC, to the Utah Museums of Natural History and Art (including Nancy Holt’s Sun Tunnels in remote western Utah), to state parks in the Sierra Nevada of California, and countries throughout Europe, along with concerts, literary readings, and theatrical performances.
