She was the head coach at Plymouth Whitemarsh (Pa.) High from 1960-74. Her teams won eight high school championships, seven of which were undefeated. Williams's coaching record at Plymouth Whitemarsh was 101-13-3.

She was an assistant coach for the U.S. squad from 1980-85. She coached Canada in the 1986 World Cup, and has also coached the Philadelphia 1, 2 and 3 teams at the National Tournament.

Williams has coached more high school lacrosse players who have become U.S. squad players than any other coach. She has helped to start lacrosse at several schools, has coached on clinics across the U.S. and Canada, and has run clinics for high school coaches in Philadelphia. She has been inducted to the University of Pennsylvania Sports Hall of Fame and is an honorary member of the United States Field Hockey Association.
