Joyce attended school at Wycombe Abbey and Dartford College in England. She arrived in the United States in 1925 to teach at Miss Applebee's camp in the Poconos. The day she was to sail home to England, she was offered a job at Wellesley College where she taught and coached field hockey. Considered by many as one of the foremothers of women's lacrosse in the U.S., she was instrumental in developing lacrosse through field hockey camps, beginning with the Pocono camp.
A pioneer and promoter of lacrosse, particularly in New England, Joyce founded the CRANBARRY Equipment Company in Marblehead, Massachusetts. CRANBARRY was the first company to specialize in women's lacrosse equipment. She provided free or low cost equipment to organizations willing to try women's lacrosse.
Joyce served as the first president of the United States Women's Lacrosse Association from 1931-35. She chaired the U.S. Team Selection Committee from 1950-51.
Joyce often drove her motorcycle to local private schools where she coached field hockey and lacrosse. She was often described as a woman way ahead of her time.
Joyce passed away in 1964.
