Mavis Derflinger, the first woman to serve on U.S. Soccer's board of directors and the first woman to be inducted into the Concacaf Hall of Fame, died on Thursday.

The English-born Derflinger was one of the founders of the Washington Area Girls Soccer League Founders and a prominent advocate for girls soccer.

She started out coaching a girls team in Lee-Mt. Vernon (Virginia) in 1969. She was elected the president of the Virginia Youth Soccer Association and was Region I director for United States Youth Soccer Association.

She became a member of the U.S. Soccer board in the early 1980s and in 1986 was elected the chairman of U.S. Youth Soccer, which put her on the USSF executive committee.

Derflinger was the head of delegation for the first women’s national team to travel overseas in 1986.
