Susan Harrington was born in Berkeley, California and has lived on the east coast, the Midwest and for the last thirty years in Fort Worth, Texas. She has traveled widely in Europe and lived in England and Denmark as a child with her family and more recently in Germany.

Susan Harrington is an experienced and highly regarded artist who has participated in numerous solo and group exhibitions throughout the United States and Germany. Her work reflects her interest in the workings of the unconscious through the use of symbols, memory and dreams. Art writer and critic Suzanne Deats has written:

Susan Harrington begins from a place of quiet mindfulness, allowing ideas to rise intuitively to conscious form, yet stopping short of description. Ms. Harrington mines the collective memory for clues and iconic inferences.

Her many honors include participating in The Advanced Critique Workshop in 2012 and the Critical Painting Workshop in 2013 with Enrique Martinez Celaya at Anderson Ranch, a Pollack-Krasner Fellowship in conjunction with an Artist in Residency at The Byrdcliffe Art Colony in 2009; a Pollack-Krasner Fellowship in 1999-2000 and a Mid-America/National Endowment for the Arts Fellowship in 1990-91. She has been an artist in residence at many programs such as The Hambidge Center for Arts and Science in 2007 and the Santa Fe Art Institute in 2004; several Vermont Studio Center residencies from 1993-2001 and an artist in residency at the Bemis Center for Contemporary Art in 1995. She is currently Associate Professor of Art at Texas Christian University, Fort Worth, Texas where she has taught drawing and painting since 1988.
