Harold Nash enters his sixth season as the Dallas Cowboys strength and conditioning coordinator, seventh overall with the team.
Nash was elevated to the lead role on the strength staff prior to the 2021 season after spending the 2020 season with the team as an assistant strength coach. In Nash's first year with theteam, he was forced to navigate a devastating tragedy when head strength and conditioning coach Markus Paul passed away mid-season. Nash was thrust into a leadership role to finish the 2020 season, and he was hired in that position full-time going forward after demonstrating tremendous poise, cohesion and leadership.
Nash continued to buoy the strength and conditioning program through the 2025 season, helping several key players return to game action from major injuries, including DeMarvion Overshown (ACL), Sam Williams (ACL) and Dak Prescott (hamstring) who returned from his injury to help ignite a Cowboys offense that ranked top five in total offense and scoring, while finishing second in the NFL in total offense (391.9 yards-per game) and scoring efficiency (48.0%). Prescott earned his fourth career Pro Bowl nod for his efforts, while Williams was named the Ed Block Courage Award recipient for the team.
In 2023 Nash worked closely with several players who returned from season-ending injuries in 2022, including Terence Steele (ACL), Jourdan Lewis (foot) and Rico Dowdle (ankle). Lewis was voted the Ed Block Courage Award recipient for his comeback.
In 2021 Nash was tasked with preparing a number of starters who missed upwards of 100 combined games due to injury in 2020, including Dak Prescott, who suffered a gruesome ankle injury in Week 5 of the 2020 season. Nash was instrumental in helping Prescott return to form in 2021, as the Dallas signal caller threw a franchise record 37 touchdown passes.
Nash joined Dallas after two previous stints in the NFL with the Detroit Lions and the New England Patriots.
In 2019 Nash served as the football performance coordinator for Detroit after working as the Lions head strength & conditioning coach his first three seasons with the team (2016-18). Nash coordinated the Lions performance program, including a comprehensive on and off-field workout plan which helped revamp the team's approach to player health and fitness to help maximize player performance and body recovery.
Prior to joining the Lions in 2016, he spent 11 seasons (2005-15) working with the New England Patriots, where he began as the team's assistant strength and conditioning coach (2005-10) before being promoted to head strength and conditioning coach in 2011. While with New England, Nash implemented the Patriots year-round conditioning program and also served as the team's player development director from 2005-10.
A former defensive back, Nash enjoyed an 11-year career in the Canadian Football League (1994-2004), including stints with the Shreveport Pirates (1994-95), Montreal Alouettes (1996-99), Winnipeg Blue Bombers (1999-2003) and Edmonton Eskimos (2004). He earned CFL All-Star recognition in 1997, 2000 and 2001.
Nash attended the University of Southwestern Louisiana (now Louisiana) and joined the football team as a walk-on, where he played defensive back for four seasons. Following his collegiate career, he signed with the New York Giants as an undrafted free agent and was a member of the team's training camp in 1993. He graduated from Southwestern Louisiana with a Bachelor of Science in Humanities.
A native of New Orleans, La., Nash and his wife, Dwan, have a son, Harold Nash III.
