Sari Garfinkel Shiren, 70, a Washington area artist and art teacher for many years, died Friday at Prince George's General Hospital. She had been suffering from diabetes.

Mrs. Shiren was born in Warsaw, Poland, and came to the United States as a child. She grew up in Brooklyn, N.Y. studied at the Art Students League in New York, and began her career as an artist there. She worked on a number of federally funded art projects before moving to Greenbelt in 1942.

She began teaching in her home in Greenbelt that year, and continued to do, so until the present. From 1955 to 1962, she also taught as a substitute teacher in the Prince George's County public schools, including Greenbelt Junior High. High Point Senior High, and Hollywood Elementary.

In the early 1960s she taught art classes in Lansburgh's department store in Langley Park. From 1962 to 1963, she worked as a computer aide for the National Aeronautics and Space Administration. In later years she volunteered art instruction to patients in area hospitals in addition to continuing art classes in her home and painting.

Mrs. Shiren was a member of the Washington chapter of the American Diabetes Association and the Washington Hebrew Congregation.

Survivors include a daughter, Lila Shiren Haslinger, of Silver Spring, and two sisters, Ciel M. Garfield, of Brooklyn, N.Y., and Ann Gilbert, of Sunrise, Fla., and one grandchild.
