Everett studied fine arts for four years at the University of Virginia (Mary Washington College) with the painter Julien Binford.
Influenced by Julian Binford's use of colour, Everett arrived in Paris in 1965 and studied at the Ecole des Beaux Arts with Maurice Biranchon.
After having taught weekly for several years at the Parisian branch of Parson's School of Art & Design, she gave annual classes from 1992 to 2002 in egg tempera technique at the National Portrait Gallery in London.
After twenty years of painting in egg tempera on paper, in 1990 she embarked on a third period of artistic development, showing a particular interest in portraiture.
In a review of Everett's portraits, Sylvu Abdel-Minem quotes the artist as saying: "I painted people who live together more by chance than by choice and who are as diverse as the colors of a palette.
