As a women with her own academic career, she gave UC Berkeley "its first experience of a Chancellor's wife who served successfully as official hostess without sacrificing her professional work" and "opened new possibilities for the spouses of subsequent Chancellors to shape their own roles". After she and her husband retired in 1980, they moved to the Washington, DC area in 1980, where Sitgreaves worked for the National Institute of Education. In 1960 she was elected as a Fellow of the American Statistical Association.
