In 1938, when she was 7, her family moved to Argentina, where her parents were Mennonite missionaries. The family returned in 1945 when she was 13. In Argentina, she learned to play piano, a skill she applied later as accompanist in church services, choirs and weddings in Puerto Rico.

She graduated from Sarasota High School and went on to Goshen College, where she obtained a Bachelor of Arts degree in education. She taught first graders in Fruitville public school in Sarasota County for two years.

In 1955, she moved to Puerto Rico and taught third and fourth graders at Escuela Menonita Betania.

She taught Sunday school children who loved her engaging teaching style. In the 1970s, she managed a self-help project that allowed rural women to earn a modest income stitching traditional Puerto Rican scenes on table cloths, table mats and cloth napkins.

She retired in 1978 and in 1982 moved with Fidel to Glendale, Calif. She served as church secretary for the Glendale Church of the Brethren. She also was secretary, treasurer and newsletter editor for the Glendale Branch of the American Association of University Women.
