Dr. Andy Barr, DPT is a globally recognized leader in high-performance sport with more than 25 years of experience working with elite teams and athletes across the NBA, NFL, EPL, MLS, PGA, WNBA, NWSL, and the Olympics. He is the founder of Quantum Performance, Quantum Movement, and the inventor of Qbands.
Originally from the UK, Andy began his career as a professional football (soccer) player with Luton Town F.C., but an early injury redirected his path. Motivated to help athletes avoid similar setbacks and unlock their full potential, he pursued physiotherapy and entered the medical world in 2001 as First Team Physiotherapist at Bolton Wanderers F.C. There, he was part of one of the most pioneering sports science and medical teams in global football, contributing to the most successful era in the club’s history.
He went on to hold senior positions at Southampton F.C. and Manchester City F.C., before moving to the United States in 2009 to join the New York Knicks. Promoted to Director of Performance and Rehabilitation, Andy played a key role in the Knicks’ historic 2013 Atlantic Division title run—the franchise’s most successful season in over 25 years. He also established the Medical and Performance Department at New York City F.C. during their inaugural MLS season, serving as Director of Medicine and Performance.
After years in team settings, Andy founded Quantum Performance to expand his impact beyond a single organization. His work is defined by a sports-specific approach to athlete care—breaking down the unique actions of each sport into their core movement patterns. This framework allows him to design individualized injury recovery and performance strategies to optimize return-to-play and long-term development. Today, he consults with professional teams and works directly with world-class athletes during their off-seasons, including helping Kevin Durant return to elite form after his Achilles tendon injury.
Alongside his consulting work, Andy leads Quantum Movement, a sports technology company specializing in motion capture–based return-to-play testing, and delivers global education programs on injury risk reduction and performance development.
