Jackie Cox enters her 14th year as head coach of Haverford College field hockey during the 2023 season. The winningest coach in program history, Cox has guided the Fords to a 126-91 record during her storied career. She reached her milestone 100th career victory during the 2019 season with a 3-2 win on the road against Eastern.

Cox’s teams have qualified for the Centennial Conference Tournament nine times during her tenure. This includes the Fords playing for the conference championship game during the 2010 and 2012 seasons. The Fords won a program-record 14 games during both of those seasons. In addition to her coaching responsibilities, Cox also assists all Haverford student-athletes as an assistant strength & conditioning coach within the athletic department.

Four players have been named NFHCA All-Americans under Cox’s guidance, including 2010 Centennial Conference Player of the Year Alex Waleko ’11. Most recently, Ravenel Davis '21 was named All-America following a stellar senior campaign that saw the forward capture Haverford's Varsity Cup award.

Sarah Waldis ’16 was additionally honored as Centennial Conference Scholar-Athlete of the Year during her senior season and is one of 29 All-Centennial Conference honorees under Cox’s leadership. Her teams have also excelled in the classroom as the Fords have earned the NFHCA National Team Academic Award every year while Haverford has accounted for 215 selections to the NFHCA Academic Squad since the 2010 season, including nine Scholars of Distinction.

A member of the National Field Hockey Coaches Association, Cox came to Haverford after spending the previous four years as the top assistant coach at her alma mater, nearby St. Joseph’s University. Cox’s duties included overseeing the team’s strength and conditioning program as well as coordinating practices and recruiting. In Cox’s four seasons at St. Joseph’s, the Hawks were twice Atlantic 10 runners-up, earned one Philadelphia City Six title, and never finished below the top four in the A-10 conference. Cox began her coaching career at her high school alma mater, Episcopal Academy, where she assisted Gina Buggy, one of the most successful scholastic coaches in Southeastern Pennsylvania.

As a player, Cox earned a reputation as a gritty and scrappy defender for the Hawks. After playing her first two collegiate seasons at Lafayette, Cox transferred to SJU where she played in 35 games on Hawk Hill, making 21 starts. She was named the Defensive Player of the Year in 2005 and also received the team's Vasquez Award for exemplifying the Jesuit value of being a "person for others." In the summer of 2006, Cox represented the United States at the Maccabi Australia International Games in Sydney.

Cox, who has earned Level I & II USA Field Hockey Coaching Accreditation, was an assistant coach for the 2011 New Jersey Region Junior High Performance Team.

Cox earned a Bachelor of Science degree in psychology and Master of Education in elementary education from St. Joseph’s University in 2006. She also is a certified Strength and Conditioning Specialist (CSCS) and has taught exercise and spinning classes at Main Line area fitness centers. She and her husband Adrian were married in June of 2010 and live in Wynnewood, Pa.
