Born in Rochester, New York to Janet and Mike Winn, Haley was raised with her three older brothers—Casey, Ryan, and Tommy—all of whom played college ice hockey. All her three older brothers became defensemen. Winn's introduction to hockey began before she could walk. Her parents recall watching her crawl to the laundry room drying rack and put on the hockey pads and jerseys of her older brothers "like dress-up." By age two, Haley was wearing skates and pushing a bucket for support on the backyard rink her father built at the family's homestead in Williamson, New York, about 30 minutes east of Rochester. A year or two later, she began playing games with and against her brothers, who were seven, six, and three years older than her, respectively. Winn later recalled watching home videos showing "several scenes where I was getting cross-checked into a snow bank" while playing with her brothers.
Winn originally played as a forward but transitioned to defense after a game in Buffalo, New York. "There was a game in Buffalo against this really fast-skating team when she came racing back from the front line and swiped the puck away from this kid who was zooming toward our goal," her mother Janet recalled. The transition showcased her natural skating ability and defensive instincts. Winn benefited from coaching by knowledgeable hockey coaches, including a stint playing for Rochester Americans Hall-of-Famer Scott Nichol. "She had the good fortune to skate for some really knowledgeable hockey coaches, who knew the game inside and out, and who welcomed her as the only girl on the team," her father said. "They really nurtured her love of the game and admired her competitiveness and drive."
Winn attended Selects Academy at Bishop Kearney for four seasons. She joined the Bishop Kearney Selects program, where she flourished. While at the Academy, she roomed with players from 18 different states and two foreign countries.
