Charlie Kosakoff is an American professional soccer player who plays as a forward for Los Angeles FC 2. Born on August 10, 2004, in San Diego, California, Kosakoff developed through Torrey Pines High School and San Diego Surf before starring at the University of Washington and helping the Huskies win the 2025 NCAA Division I national championship.
Soccer has strong roots in Kosakoff’s family. His father, Joel Kosakoff, coached at Torrey Pines High School while Charlie was playing there, and his older brother, Jake Kosakoff, was also a standout soccer player at Torrey Pines. Archival family records further establish Charlie and Jake as members of the same close Kosakoff family in the San Diego area.
Information about Charlie’s mother is less definitive. Public school records repeatedly associate Joel Kosakoff with Sara McMenamin, but the available sources reviewed do not explicitly identify her as Charlie’s mother. For that reason, her relationship to Charlie should not be presented as confirmed without stronger evidence.
As of now, there is also no reliable public confirmation that Charlie Kosakoff has a girlfriend, wife or children.
Does Charlie Kosakoff Have a Girlfriend?
As of now, Charlie Kosakoff has not publicly confirmed having a girlfriend.
Coverage from LAFC, the University of Washington, Ballard FC and his earlier San Diego soccer career has concentrated almost entirely on his performances and development as a player.
No reliable club, university or established sports source reviewed identifies a romantic partner.
Because social-media photographs or interactions do not by themselves establish a relationship, it would be inappropriate to name someone as Kosakoff’s girlfriend without confirmation from Charlie himself or a reliable source.
Is Charlie Kosakoff Married?
There is no reliable public confirmation that Charlie Kosakoff is married.
Official profiles from LAFC2 and the University of Washington do not identify a wife or spouse. His public biography remains overwhelmingly focused on soccer and education rather than his private relationships.
Does Charlie Kosakoff Have Children?
As of now, there is no reliable public information confirming that Charlie Kosakoff has children.
Neither LAFC nor Washington identifies him as a father, and established coverage of his professional and college career does not mention a son or daughter.
Who Are Charlie Kosakoff’s Parents?
Charlie Kosakoff’s father is Joel Kosakoff, who has been involved in soccer as a coach in San Diego.
Torrey Pines boys soccer coverage directly identifies Charlie as Joel’s son. Joel served as a varsity assistant coach for the Falcons while Charlie was one of the team’s leading attackers.
Information about Charlie’s mother is less clear. School donor records from the Del Mar and Torrey Pines communities repeatedly list Joel Kosakoff and Sara McMenamin together. However, those records do not explicitly say that Sara is Charlie’s mother.
For that reason, the strongest verified conclusion is that Joel is Charlie’s father, while his mother’s identity has not been directly confirmed in a reliable biographical source.
Who Is Charlie Kosakoff’s Father, Joel Kosakoff?
Joel Kosakoff is Charlie Kosakoff’s father and has a background in soccer coaching.
Torrey Pines High School records show Joel working as a varsity boys soccer assistant coach during the period when Charlie was playing for the school.
In March 2022, Torrey Pines coverage specifically described Charlie as Joel’s son while reporting that the young forward had temporarily left the high-school team to participate in trials with San Diego Loyal.
Joel also took charge of Torrey Pines in at least one important match when head coach Andrew Hargreaves was unavailable, demonstrating that he was actively involved with the program rather than simply watching his son from the sidelines.
Charlie Kosakoff Grew Up in a Soccer Family
Charlie was exposed to soccer through both his father and older brother.
Joel coached the sport, while Jake Kosakoff was already competing at a high level for Torrey Pines when Charlie joined the varsity squad.
During the 2019-20 season, Jake was a senior midfielder while Charlie was only a sophomore forward. Both appeared on the Torrey Pines varsity roster at the same time.
That meant Charlie entered high-school soccer with both his father on the coaching staff and his older brother on the field.
Does Charlie Kosakoff Have Siblings?
Charlie Kosakoff has an older brother named Jake Kosakoff.
The family relationship is supported by archival records concerning their uncle, Alan Kosakoff. A San Diego Union-Tribune obituary identified Jake and Charlie as Alan’s nephews while identifying Joel Kosakoff as Alan’s brother.
The age information in that record also fits their later school careers: Jake was listed as two years older than Charlie.
Both brothers subsequently played varsity soccer for Torrey Pines High School.
Who Is Charlie Kosakoff’s Brother, Jake Kosakoff?
Jake Kosakoff is Charlie’s older brother.
Jake was a talented soccer player at Torrey Pines and earned significant recognition during his senior season. He was selected to the San Diego Section All-CIF First Team in 2020.
TopDrawerSoccer also recognized Jake among California’s leading winter high-school players, listing him as a senior midfielder while Charlie was listed as a sophomore forward.
The brothers therefore shared at least one Torrey Pines varsity season together.
What Does Jake Kosakoff Do Now?
Jake ultimately followed an academic path rather than a professional soccer career.
He attended the University of California, San Diego, where he studied applied mathematics and computational physics.
UC San Diego recognized Jake with Dean’s Undergraduate Awards for Excellence in both mathematics and physics.
He later continued at UC San Diego as a graduate student in mathematics and has worked as a teaching assistant.
His path highlights the different directions taken by the two brothers: Charlie pursued professional soccer, while Jake moved toward advanced academic research.
Charlie and Jake Played Together at Torrey Pines
The 2019-20 Torrey Pines varsity roster included both brothers.
Jake wore No. 13 and was a senior, while Charlie wore No. 19 and was a sophomore.
Both were recognized individually during that season. Jake earned All-CIF honors, while Charlie emerged as one of the region’s most promising younger forwards.
Charlie later produced one of the defining performances of his high-school career when he scored a hat trick to help Torrey Pines win a CIF championship.
Charlie Kosakoff’s Family Connection to Torrey Pines Soccer
The Kosakoff family’s connection with Torrey Pines extended beyond Charlie and Jake simply attending the school.
Their father Joel served on the coaching staff, while both sons competed at varsity level.
Official school-district documents from 2021 list Joel Kosakoff as a varsity assistant coach. Interestingly, the same records also list Jake Kosakoff as a varsity assistant coach that year, showing that Jake remained involved with the program after finishing his own high-school playing career.
Soccer was therefore a shared activity across multiple members of the Kosakoff family.
Who Is Charlie Kosakoff’s Mother?
Charlie’s mother has not been explicitly identified in the reliable player biographies reviewed.
Public education-related records from Del Mar repeatedly list Joel Kosakoff and Sara McMenamin together as supporters or donors. Their names also appear together in Torrey Pines-area education records.
Those records establish an association between Joel and Sara but do not directly state that Sara is Charlie’s mother.
Because family relationships should not be inferred solely from shared school records, this profile does not identify Charlie’s mother by name without stronger confirmation.
Charlie Kosakoff’s Grandparents and Uncle
Archival family records provide additional information about Charlie’s paternal side.
His late uncle Alan Jay Kosakoff was Joel Kosakoff’s brother. Alan attended Torrey Pines High School himself and later graduated from the University of California, Berkeley with degrees involving electrical engineering, computer science and materials science.
Alan’s obituary named Harold Kosakoff as his father and Arlene Kosakoff as his mother. The same obituary identified Jake and Charlie as his nephews.
This provides a documented multigenerational connection between the Kosakoff family and the San Diego area.
Charlie Kosakoff’s Childhood in San Diego
Kosakoff grew up in the San Diego area and attended Torrey Pines High School.
His youth career combined school soccer with elite club competition. He played for San Diego Surf and also spent time around San Diego Loyal’s professional setup.
Washington’s official recruiting profile notes that Kosakoff helped San Diego Surf win both a Surf Cup championship and an ECNL California championship.
He also led the club in scoring.
Charlie Kosakoff’s Serious Injury and Comeback
Kosakoff faced a major setback during his high-school career when he suffered a serious leg injury.
San Diego sports coverage reported that Charlie returned from a broken femur and produced a remarkable performance in the CIF championship.
He scored a hat trick as Torrey Pines defeated Del Norte 4-1 to win the title.
The performance earned Kosakoff recognition as one of the San Diego Sports Association’s Stars of the Month.
Charlie Kosakoff at the University of Washington
Kosakoff joined the University of Washington in 2023.
He initially planned to study business and later pursued real estate as his listed university major.
After making 12 appearances as a freshman, his role increased considerably during his sophomore season. He scored five goals and provided four assists in 2024.
His biggest breakthrough came in 2025.
Charlie Kosakoff and Washington’s NCAA Championship
The 2025 season turned Kosakoff into one of the most important players on Washington’s national-championship team.
He delivered repeatedly during the NCAA Tournament.
Kosakoff provided the game-winning assist against Oregon State, scored the decisive goal against Stanford in the Sweet 16 and scored again against Maryland in the quarterfinal.
He then produced a goal and an assist against Furman in the College Cup semifinal.
In the championship match against NC State, Kosakoff supplied an assist on Washington’s golden goal as the Huskies captured the first NCAA men’s soccer championship in program history.
He finished the season with 11 goals and seven assists and earned College Cup All-Tournament and All-Big Ten recognition.
Charlie Kosakoff’s Success With Ballard FC
Before Washington’s championship season, Kosakoff also enjoyed an outstanding 2025 campaign with Ballard FC in USL League Two.
He led the Seattle club with nine goals, including five during the playoffs.
Kosakoff scored the winning goal in the conference final, added two more in the national semifinal and scored Ballard’s goal in the USL League Two championship match.
His performances for Ballard and Washington helped establish him as a professional prospect.
Charlie Kosakoff Joins LAFC2
LAFC2 signed Kosakoff ahead of the 2026 MLS NEXT Pro season.
The agreement runs through 2026 with a club option for 2027.
LAFC highlighted his strong performances with Ballard and Washington when announcing the deal.
Kosakoff quickly became a regular part of the LAFC2 attack and continued scoring during his first professional season.
Charlie Kosakoff’s LAFC First-Team Opportunity
His performances eventually earned him an opportunity with LAFC’s Major League Soccer squad.
In August 2026, LAFC signed Kosakoff and goalkeeper Mark Gamez to short-term first-team agreements.
Kosakoff was subsequently included in LAFC’s MLS matchday squad against D.C. United, although he did not enter the game.
His first-team involvement nevertheless represented another significant step for a player whose career began in San Diego alongside his father and older brother.
