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.
