Jannik Sinner’s biggest backing has always come from home, even when his family cannot be in the stands. As he looks to defend his Wimbledon title, the people closest to him remain a major part of the story behind his success.
Sinner has spoken openly about the sacrifices his parents made after he left home at 13 to train at a tennis center. He said that decision was difficult for him, but even harder for his mother and father, who also wanted to see him grow up.
He later said he has missed time with his parents, and that he wants to catch up whenever he can. Sinner also noted that his maternal grandparents are still alive, which helps explain why his mother wants to stay close to home and spend as much time with them as possible.
His parents built their lives around hard work
Growing up, Hanspeter Sinner, who is also known as Johann, and Siglinde worked at a ski lodge. They now run their own guest house, Haus Sinner, and those work commitments often keep them from attending their son’s matches.
Sinner told reporters in 2024 that he loves that about them because “They’re not changing anything with me.” He also said earlier this year that his mother is “definitely a role model,” and described both parents as a true inspiration.

Mark Sinner keeps a close bond from afar
Jannik Sinner’s brother Mark was born in Russia in 1998 and was adopted by the family when he was nine months old, two years before Jannik was born in 2001. Mark now works as a fire brigade instructor in South Tyrol, Italy.
Mark said he is used to not seeing his brother at home, but values the times when he returns. He also said the two keep in touch by phone almost daily, and that Jannik has always remained calm both on and off the court.
That same steady image runs through the family’s description of him. From his parents’ long workdays to his brother’s life in South Tyrol, Sinner’s support system appears to be built on routine, distance, and a strong sense of loyalty.
