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 played college soccer at Middlebury and coached Dorseys's 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 records, 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]
North Carolina Tar Heels
Soccer
Dorsey chose to attend the University of North Carolina because it was a school where she could play both soccer and lacrosse, doing so on a lacrosse scholarship.[4][8] She was the sixth person in school history to play for both programs.[1] In her freshman season in 2019, she appeared in all 27 games (18 starts) for the soccer team as they won the ACC tournament and reached the NCAA championship game, where they lost to Stanford on penalties.[1][9] She was named to the Freshman Best XI second team by TopDrawerSoccer.[10] She started all 12 games in the first half of the 2020 season, then sat out the spring half (held due to the COVID-19 pandemic) while with the lacrosse team.[1]
Dorsey had an injury at the start of her junior season in 2021, returning to make 8 appearances (6 starts) and score her first goal, which came against Boston College.[8][11] In her senior season in 2022, she started 22 games and helped North Carolina record one of the best defenses in the ACC.[1] During the NCAA tournament, she scored her second career goal in a 3–2 semifinal win against Florida State, before finishing runner-up to UCLA in the title game.[12][13] She missed the entire 2023 season due to an ACL injury she suffered with the lacrosse team in the spring.[1]
Lacrosse
Dorsey played in all 7 games (2 starts) for the Tar Heels lacrosse team as a freshman in 2020, before the season was cancelled due to the pandemic. She appeared in 19 games in her sophomore season in 2021, helping North Carolina go undefeated on the way to the semifinals of the NCAA tournament, where they lost to eventual champions Boston College.[1][14] In her junior season in 2022, she took on a bigger role and played 19 games (15 starts) as they went undefeated to win the NCAA championship, the program's third national title and first since 2016.[1][15] She started the first 11 games of her senior season in 2023, before suffering an ACL tear that ended her college career.[1][13]
Club career
Dallas Trinity
The North Carolina Courage selected Dorsey in the third round (40th overall) of the 2024 NWSL Draft.[16] She was signed to a three-year contract.[17] On August 9, the Courage announced that she would be loaned to USL Super League club Dallas Trinity FC for the rest of the year ahead of the league's inaugural 2024–25 season.[18] 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 which marked Dorsey's return to action after her ACL injury in 2023.[19] She started 13 games for Trinity during the fall series and played more minutes for the team than anyone except Amber Brooks, helping them sit second in the league standings.[20] She was waived by the Courage on December 9, 2024,[21] and Trinity announced they had signed her themselves on January 24, 2025.[22]
