Introduction

Hanspeter Sinner is widely known as the father of Italian tennis star Jannik Sinner, but his own life and career are interesting in their own right. A professional chef from South Tyrol, Hanspeter spent decades working in mountain hospitality before becoming part of his son’s professional tennis journey. He is also known as Johann Sinner in some English-language sources, while Italian and other reports frequently use Hanspeter.

For many years, Hanspeter and his wife, Siglinde Sinner, lived a quiet working life in Sexten, a mountain community in northern Italy. Both worked at the Talschlusshütte mountain refuge in the Fischleintal, with Hanspeter working in the kitchen and Siglinde serving guests. Their long working hours helped shape the environment in which Jannik grew up. Rather than pushing their son toward a particular career, they gave him the freedom to discover his interests and make important decisions for himself.

Today, Hanspeter’s name is closely connected to the remarkable rise of Jannik Sinner. However, his contribution has never been limited to being the parent of a famous athlete. His career as a chef, his work ethic, his connection to South Tyrol, and his practical support for Jannik have all become important parts of the family’s story.

Who Is Hanspeter Sinner?

Hanspeter Sinner is a South Tyrolean chef and the father of Jannik Sinner. He was born in 1964, according to Italian reporting, and spent much of his professional life in the mountain region around Sexten and the Fischleintal. His career was centered on cooking and hospitality rather than sport, although sport naturally became a major part of family life because of Jannik’s interests.

Some international sources refer to him as Johann Sinner and explain that he is also known as Hanspeter Sinner. This difference in naming can make online information about him confusing, but the reports clearly refer to the same person: Jannik Sinner’s father and a longtime professional chef.

Unlike his son, Hanspeter has generally avoided the spotlight. He has not attempted to build a public career from his relationship with one of the world’s leading tennis players. Instead, he has continued to be associated with his family, cooking, South Tyrol, and the simple lifestyle that existed before Jannik became internationally famous.

Hanspeter Sinner’s Life in South Tyrol

South Tyrol has played an important role in the Sinner family’s identity. Jannik was born in Innichen and grew up in Sexten, surrounded by the Dolomites. His childhood was very different from that of many professional tennis players because his early environment was dominated by mountains, skiing, hospitality, and outdoor activities.

Hanspeter and Siglinde worked at the Talschlusshütte mountain refuge. Their jobs demanded long hours, and Jannik has spoken about how his parents were often working when he returned home from school. Their schedule meant that he learned to spend time independently, with sports becoming an important part of his childhood.

This background helped shape the values that Jannik later carried into professional tennis. He has repeatedly talked about the importance of hard work and has credited his parents with giving him the mentality needed to pursue difficult goals. Their lifestyle demonstrated that achievement comes from consistency and effort rather than shortcuts.

Hanspeter’s life also reflects the culture of the region. South Tyrol has a strong tradition of mountain tourism, hospitality, skiing, and outdoor sports. The Sinner family was part of that environment, and it provided Jannik with a natural introduction to physical activity from a very young age.

His Long Career as a Professional Chef

Hanspeter’s main profession has been cooking. Reports state that he spent around 40 years working in kitchens, including more than 20 years at the Talschlusshütte in the Val Fiscalina. During that time, he became an experienced chef and an important figure in the local hospitality community.

His work involved much more than simply preparing meals. Working in a mountain refuge requires discipline, organization, consistency, and the ability to serve visitors in a demanding environment. Over many years, Hanspeter developed the skills that would later become useful in an entirely different setting: professional tennis.

Italian reporting has described him as a reference point for the local community and as someone who also helped younger cooks learn their profession. His experience therefore extended beyond his own kitchen responsibilities.

Cooking also became part of his identity. Jannik has explained that his father has spent decades in the kitchen and that cooking is essentially his father’s life. This is one reason Jannik later welcomed him into his professional team in a culinary role.

Hanspeter and Siglinde Sinner as Parents

Hanspeter and his wife, Siglinde, raised Jannik and his older adopted brother, Mark. Siglinde also worked at the mountain refuge, where she was responsible for serving and welcoming guests. Their family life was therefore closely connected to the hospitality industry.

The couple’s parenting approach has attracted attention because they did not force Jannik to choose tennis. As a child, he participated in several sports and became particularly successful in skiing. He competed at a high level as a young skier and won important junior events before eventually deciding that tennis was the sport he wanted to pursue.

Jannik has publicly praised his parents for giving him this freedom. After winning his first Grand Slam title at the 2024 Australian Open, he spoke about how his parents had allowed him to choose what he wanted and had not put excessive pressure on him. Their approach gave him the opportunity to discover his own interests and take responsibility for his decisions.

This freedom became particularly important when Jannik eventually left home as a teenager to pursue more serious tennis training.

Hanspeter’s Influence on Jannik’s Sporting Development

Hanspeter was not the professional tennis coach responsible for developing Jannik’s technical game. Instead, his influence was more personal. He helped introduce Jannik to tennis and encouraged him to participate in sport while allowing him to develop his own interests.

Jannik’s childhood in the mountains meant skiing was initially a major part of his life. He began skiing at around three years old and competed in ski races as a child. He also played football and tennis. His parents supported all these activities rather than deciding from the beginning that he had to become a tennis player.

One of the most important decisions came when Jannik was around 13 or 14 and moved to Bordighera to train more seriously. Leaving his family and familiar surroundings at such a young age was a major step. His parents trusted his decision and supported him even though it meant that their family life would change.

That trust became a defining part of Jannik’s relationship with his parents. Instead of controlling his career, they provided a foundation and allowed him to take responsibility for the direction he wanted to follow.

Hanspeter Sinner as Jannik’s Tour Chef

Hanspeter’s professional cooking skills eventually brought him directly into Jannik’s tennis career. Beginning around 2023, he started joining his son’s team during parts of the professional tour as a chef. This was particularly useful during longer trips when Jannik and his team stayed together in the same accommodation.

Jannik has explained that having his father cook for him is about more than food. It also means having a family member nearby during a demanding period of his career. For a player who spends much of the year traveling internationally, that familiar connection can provide a sense of comfort and normality.

Hanspeter’s role also demonstrates how the Sinner family combines professional support with family relationships. He did not suddenly become a tennis coach or manager. Instead, he contributed using the skill he had developed over decades: cooking.

The arrangement has also allowed father and son to spend more time together. Jannik has spoken about how little time they had together when he was growing up because both parents worked long hours. Having Hanspeter on the road therefore became an opportunity to recover some of that lost family time.

The Family’s Strong Work Ethic

Work ethic is one of the most frequently mentioned themes when Jannik talks about his parents. Hanspeter and Siglinde worked long shifts while raising their children, and Jannik saw their commitment from an early age.

Jannik has described returning from school and finding that his parents were still working. Instead of viewing their absence simply as a disadvantage, he came to understand it as an example of commitment. Their lifestyle showed him that achieving something meaningful requires effort and patience.

That mentality became visible in Jannik’s approach to professional tennis. His rise was not based on an overnight transformation. He progressed through junior tennis, professional competition, the ATP Tour, and eventually Grand Slam success.

Hanspeter’s influence can therefore be understood through values rather than tennis technique. Discipline, independence, humility, and persistence became part of Jannik’s character, and those qualities are closely associated with the family environment in which he grew up.

Hanspeter’s Private Life and Connection to Home

Despite his son’s worldwide fame, Hanspeter has remained strongly connected to South Tyrol. The family’s roots in Sexten continue to be important, and the Sinners have maintained a relatively simple lifestyle despite Jannik’s enormous success.

Reports have noted that the family has remained grounded even as Jannik became a global sports star. Hanspeter has continued working rather than completely abandoning his professional identity because of his son’s achievements. In 2025, for example, Jannik explained after the French Open that his father could not attend his historic final because he was working.

That incident became a powerful illustration of the family’s attitude. Jannik’s success may have changed his public profile, but it did not completely change the family’s daily values. Hanspeter remained a working chef while his son competed for one of the biggest trophies in tennis.

The family has also tried to protect its privacy. Jannik has spoken about how important his family is to him and has indicated that he dislikes unnecessary attention directed toward them.

Hanspeter Sinner’s Importance to Jannik’s Success

It is difficult to separate Jannik Sinner’s success from the environment created by his parents. Hanspeter did not produce his son’s tennis technique, but he helped provide something equally important: a stable foundation.

Jannik was allowed to make decisions, explore sports, and eventually choose tennis. His parents supported him when he moved away for training and continued to encourage him without demanding that he meet unrealistic expectations.

Hanspeter’s influence is also visible in the way Jannik talks about work. The tennis star has repeatedly emphasized his gratitude for his parents and their example. Their ability to work hard without seeking attention appears to have influenced his own attitude toward fame.

Even now, Hanspeter’s role continues. He can be found supporting his son through cooking, family presence, and occasional travel rather than through public interviews or celebrity appearances. His contribution is practical, personal, and deeply connected to the family.

Conclusion

Hanspeter Sinner’s story is an important part of the larger story behind Jannik Sinner’s rise to the top of world tennis. A professional chef from South Tyrol, Hanspeter spent decades working at the Talschlusshütte mountain refuge alongside his wife, Siglinde. His career was built around cooking, hospitality, discipline, and service, long before his son’s name became famous around the world.

As a father, his greatest contribution was not coaching tennis but creating an environment in which Jannik could discover his own path. Jannik was allowed to ski, play football, play tennis, and eventually decide for himself that tennis was the sport he wanted to pursue. His parents supported him when he left home as a teenager and continued to provide encouragement without putting excessive pressure on him.

Hanspeter later found a unique way to become part of Jannik’s professional career by using the skill he had developed throughout his working life. As a chef for parts of Jannik’s tennis tour, he has been able to provide familiar food while also spending valuable time with his son.

Ultimately, Hanspeter Sinner represents the quiet family support behind a global sports career. His story is one of hard work, humility, family, and independence. While Jannik Sinner’s name is now known around the world, the values that helped shape him were developed much earlier in the mountains of South Tyrol, within a hardworking family led in part by his father, Hanspeter Sinner.
