Minich, who attended PAFA in 1954 and 1955, is known for her abstract, mixed-media paintings on wood that are often inspired by architectural elements. She refers to them as "painting/constructs" and incorporates "intentionally ordinary and mundane" found objects into her work. Minich also creates her own wooden supports and framing treatments.
Minich's work has been on view in well over a dozen solo shows and many more group exhibitions. Her work is collected by museums and private collectors, and she is the recipient of awards including a Pollack–Krasner Award, the Leeway Foundation's Bessie Berman Painting Award, and a MacDowell Colony Fellowship. She lives and works in Philadelphia.
