Who are Jannik Sinner’s parents? Meet dad Johann and mom Siglinde

 Jannik Sinner, the world No. 1 tennis player and four-time Grand Slam champion, credits much of his drive to his parents, Johann and Siglinde Sinner. The couple worked for years at a ski lodge in the Italian Dolomites before the family established their own guest house. Johann occasionally joins Sinner on tour as a personal chef, while Siglinde is known to struggle watching her son’s matches live due to nerves. Both were present at Wimbledon 2025 when Sinner defended his title. Jannik Sinner, the world No. 1 tennis player and four-time Grand Slam champion, credits much of his drive to his parents, Johann and Siglinde Sinner.
