Dorsey was born in Baltimore, Maryland, to Van and Jessica Dorsey, and has an older sister.[1] She began playing soccer at age five and lacrosse shortly thereafter.[2] Her father, a former college soccer player for the Middlebury Panthers, coached her first club team when she was six or seven.[1][3]
Dorsey played high school soccer, basketball, and lacrosse at McDonogh School, a private prep school in Owings Mills, Maryland. Her lacrosse team went undefeated to win IAAM championships in 2016, 2017, and 2019, with Dorsey in midfield; she sat out the 2018 season after suffering an ACL tear.[2][4] She also won three IAAM titles with the soccer team in 2015, 2017, and 2018, playing as a forward for her first three seasons and right back in her senior year.[5][6] That year, after captaining both teams to undefeated record, she received All-American honors in both sports and was named The Baltimore Sun's high school female athlete of the year.[4][7] While in high school, she played club soccer for the Bethesda Soccer Club and club lacrosse for Sky Walkers Lacrosse.[1][3]
College career
Dorsey chose the University of North Carolina as a school where she could play both soccer and lacrosse (on a lacrosse scholarship).[4][8] She joined the soccer team's starting lineup during the 2019 season, helping the team to win the ACC tournament and reach the NCAA championship game.[9][10] She was recognized by TopDrawerSoccer.com with Freshman Best XI and second-team Best XI honors.[11] She became the sixth person in school history to play for both programs after debuting for the lacrosse team in the spring of 2020.[1] As a sophomore, she started for the soccer team throughout the fall of 2020, then helped the lacrosse team go undefeated on the way to the 2021 NCAA semifinals.[1][12]
Dorsey sat out the start of her junior soccer season due to injury but returned later in the year and recorded her first career goal, a tap-in to force overtime against Boston College in October 2021.[8][13] In the spring of 2022, as she switched from midfield to defense, she helped the lacrosse team go undefeated to win the NCAA championship.[14] Later that year, she helped the soccer team reach the final of the NCAA tournament, anchoring a conference-best back line and scoring the third goal in a 3–2 win over Florida State in the NCAA semifinals, but they finished runners-up in the title game.[15][16] She suffered an ACL tear ending her senior lacrosse season in the spring of 2023.[1][16]
On August 9, 2024, ahead of the inaugural 2024–25 USL Super League season, Dorsey was loaned to Dallas Trinity FC for the rest of the NWSL season.[19] She appeared in the starting lineup of Trinity's first-ever game on August 18, which they drew 1–1 to Tampa Bay Sun FC, and marked Dorsey's first game since her ACL injury in 2023.[20]
