Ann Sink (Ann Breese, Ann Sink White) was born in Illinois in 1924. Her father, a pilot and a crew member on the first transatlantic flight (1919), made an emergency landing in New Mexico while working for Pan American Airways. In 1928, he moved the family to Santa Fe, settling on Upper Canyon Road. Ann developed an interest in art at a young age and was immersed in the rich artistic culture of Santa Fe. The artist Randall Davey was a neighbor and family friend, Ann made frequent visits to his studio while growing up. Andrew Dasburg was among her neighbors and Ann knew Gustave Baumann as she was friends with his daughter. Other family friends included Will Shuster and Mabel Dodge Luhan. She attended the Sandia School in Albuquerque, New Mexico where she received instruction in drawing and painting from artists including Raymond Jonson and Kenneth Adams. She also took summer classes in art in Santa Fe. Following graduation, she attended Bennington College in Vermont where she studied under Paul Feeley along with fellow student, Helen Frankenthaler. During her time at Bennington, Ann fulfilled her required term studying away from campus studying under Diego Rivera in Mexico City.
Ann returned to New Mexico following her graduation in 1947. She met and married Charles Sink, an architect. Charles' work took them to Venezuela where Ann continued her art studies. After two years abroad, the couple settled in Denver, Colorado where Charles opened an architectural office. In 1954, the young family moved to New York for two years where Charles worked with his former Harvard classmate and fellow architect, I.M. Pei. In 1956, the couple returned to Colorado where Charles served as the Denver associate of I.M. Pei's architecture firm. While raising her young children, Ann continued to paint. In addition to representational art, she worked in styles of Pure and Referential Abstraction, Abstract Expressionism and Color Field painting. She also used referential abstraction to paint the adobe buildings and New Mexico landscapes that surrounded her while growing up. In the 1960s, Ann Sink painted modernist landscapes of the American southwest including Colorado, New Mexico, Montana, and Arizona. Throughout the 1950s and 1960s, Sink was active in the Denver artist community. She exhibited her work at local galleries, the Jewish Community Center Annual Invitationals, The Colorado Historical Society (now History Colorado), the Gilpin County Arts Society and the Rocky Mountain National Watercolor Show at Foothills Gallery in Golden. She co-founded the Alliance for Contemporary Art (AFCA) and was a founding member of the Nine, a group of local artists and artisans. She volunteered extensively and was on the board of the Colorado Coalition for the Prevention of Nuclear War.
In 1969, Ann earned her teaching certificate in art from the University of Denver (DU). She gave instruction in art at the Jewish Community Center, Littleton schools, Cherry Creek schools and the Denver Art Museum.
She married Edward White following a divorce from Charles Sink in the 1970s.
