Gill was born in in New Jersey, but spent her early years in Bethesda, Maryland, where she first studied ceramics in high school. She entered a piece in a competition for high school students and won a scholarship for the Corcoran School of Art in Washington, D.C. She studied painting at the Rhode Island School of Design, graduating in 1971 with a Bachelor of Fine Arts. Gill continued her ceramics studies at the Kansas City Art Institute (KCAI) with Ken Ferguson (see Ferguson’s 1960s Bottle); and then on to Alfred University, New York for her Master of Fine Arts in 1978. She met her husband, John Gill (also a well-known ceramist) at Kansas City Art Institute. They held several teaching positions across the country and both became Professors of Ceramic Art at Alfred University, New York, teaching there for more than thirty years (1984-2017).
