Jannik Sinner’s family background reveals the roots of his discipline and humility

His father Johann brings culinary expertise to the tennis circuit

Johann Sinner, Jannik’s father, has worked as a professional chef for over four decades. Originally employed at the Talschlusshütte Hut ski lodge in Sexten, Italy, Johann’s culinary skills have become a unique asset to his son’s tennis career. He now occasionally travels with Jannik as part of his team, preparing meals and offering a comforting presence during tournaments. Johann’s dedication to his craft and quiet support have helped shape Jannik’s work ethic and independence.

His mother Siglinde supported the family with hospitality work

Siglinde Sinner, Jannik’s mother, worked as a waitress at the same ski lodge where she met Johann. Her role in the hospitality industry demanded long hours and resilience, qualities that Jannik credits for his own mental strength. Though she prefers to stay out of the spotlight, Siglinde has been a constant source of emotional support. She often chooses to watch matches from home, finding the intensity of live competition overwhelming, yet remains deeply involved in her son’s journey.

His brother Marc shares a quiet bond and different passions

Jannik has an older brother named Marc, who was adopted by Johann and Siglinde shortly after birth. Marc is known for his love of Formula 1 and maintains a close relationship with Jannik despite their differing interests. While Jannik travels the world competing, Marc enjoys attending F1 events and playing golf with his brother when time allows. Their connection reflects the family’s emphasis on freedom and individuality, values that have allowed each member to pursue their own path.

A family built on hard work and quiet strength

The Sinner family’s story is one of modest beginnings and unwavering support. From ski lodge shifts to international tennis courts, Johann and Siglinde have instilled in Jannik a sense of responsibility, independence, and gratitude. Their decision to let him move away at age 14 to pursue tennis was a pivotal moment, demonstrating their trust in his ambition. Today, Jannik’s success is deeply intertwined with the quiet sacrifices and enduring love of his family.
