Charities and Causes

John Isner raises funds for the UNC Lineberger Comprehensive Cancer Center in Chapel Hill, North Carolina. The UNC Lineberger Cancer Center is one of the leading treatment facilities in the nation and is where John's mother, Karen, was successfully treated during her two battles with colon cancer.


John Isner holds the Isner Charity Challenge annually. "I'm excited to have the opportunity to support an organisation that has given so much to my family," says Isner. "UNC Lineberger continues to make remarkable strides in the fight against cancer, and I'm looking forward to celebrating and supporting their work during the event."

The third edition, held in December 2012, was supported by rising WTA star Christina McHale, former UNC All-American and ATP pro Nick Monroe, and celebrity emcee Wayne Bryan, father and former coach of the World No. 1 Doubles Team, Mike and Bob Bryan.

The fourth edition of the Ebix Charity Challenge raised $100,000. Isner and former World No. 1 Andy Roddick hosted a youth clinic and played an exhibition match watched by more than 1400 fans at the University of North Carolina at Greensboro.

In 2014, Isner received a $15,000 grant from ATP ACES for Charity for the UNC Lineberger Comprehensive Cancer Center.
