Quick Bio

Who is Harald Leemann?

Harald Leemann is a Swiss physician whose professional life sits at the intersection of orthopaedic medicine and elite sport. As deputy head of sports medicine at Kantonsspital Zug, one of the most respected hospital institutions in the canton of Zug, and as official association doctor of Swiss Tennis since April 2024 under a contract running to the end of 2026, he occupies one of the most institutionally significant medical roles in Swiss sport. His work covers the full spectrum of the Swiss national tennis programme, from the women’s Billie Jean King Cup team to Davis Cup and national training support.

His public profile in Switzerland is that of a respected sports medicine professional who has served both winter and summer sport disciplines at the national federation level. The broader international public knows him primarily through his marriage to Martina Hingis, the Swiss tennis player who was ranked world number one for 209 weeks, won five Grand Slam singles titles, and is widely considered one of the most tactically intelligent players in the history of the women’s game. Leemann and Hingis married in July 2018, welcomed their daughter Lia in March 2019, and announced their separation in 2022. His connection to Hingis brought him into a degree of public attention that his own professional career, grounded in the typically private world of medical practice, would not have generated. Stories of professionals who built distinguished specialist careers alongside public-facing relationships are among those documented across biographical profiles on this site.

What distinguishes Leemann’s biography from the typical celebrity-adjacent figure is the substantive and independently documented professional career that predates, runs through, and continues after his marriage to Hingis. He was already team doctor to the Swiss Ski Freestyle national team for over six years before his 2016 meeting with Hingis through the Fed Cup. He brought Martina Hingis into his professional orbit rather than the other way around. That distinction matters for understanding who Harald Leemann is as a subject.

Education and Qualifications

Medical Training and Specialisation

Harald Leemann holds a medical degree (Dr. med.) and a Master of Science from Donau-Universitat Krems in Austria, one of Europe’s leading continuing education universities for medical professionals. He holds the FMH specialist title in orthopaedics and traumatology of the locomotor apparatus, with a subspecialisation in sports medicine (SGSM) from the Swiss Society of Sports Medicine.

The FMH title, awarded by the Federation of Swiss Physicians, is Switzerland’s primary specialist certification system and requires completion of a defined curriculum, specialist examinations, and documented clinical practice hours within the qualifying specialty. Leemann’s FMH in orthopaedics and traumatology reflects the core clinical training that underpins his hospital work at Kantonsspital Zug, where he operates as a senior physician in the orthopaedic and traumatology department. The SGSM sports medicine specialisation represents an additional layer of qualification specific to the athletic and exercise medicine context in which he applies that training.

His MSc from Donau-Universitat Krems reflects engagement with postgraduate research and continuing education at an institutional level, demonstrating an interest in the academic dimensions of his specialty alongside clinical practice. His ResearchGate profile lists three publications with 33 citations, confirming a modest but genuine contribution to the medical literature, including a case report on fluoroquinolone-induced bilateral quadriceps tendon rupture and a German-language article on prosthetic management of complex proximal humeral fractures.

Tennis Qualification

In addition to his medical qualifications, Harald Leemann holds a certified tennis instructor qualification from the Swiss Professional Tennis Association (SPTA), making him a dually qualified professional in both the medical and technical coaching dimensions of the sport he serves at the national level.

The SPTA qualification is not a nominal credential: it represents formal training in tennis technique, coaching methodology, and player development as understood by Switzerland’s professional tennis governing body. For a sports medicine physician working specifically with elite tennis players, a coaching qualification provides an unusually integrated understanding of the biomechanical demands, movement patterns, and training loads that produce the injuries he is called upon to treat and prevent. That dual qualification is uncommon and reflects a genuine personal investment in tennis beyond its role as a professional context.

Professional Career

Kantonsspital Zug

Harald Leemann serves as deputy head of sports medicine at Kantonsspital Zug, located in Baar in the canton of Zug. Kantonsspital Zug is the principal hospital of the canton and operates as a leading centre for sports medicine and orthopaedic care in central Switzerland, with medical partnerships extending across multiple elite sport organisations in the region.

His institutional role at Kantonsspital Zug places him within a sports medicine department that serves elite athletes and recreational sportspeople across a broad range of disciplines. The hospital’s sports medicine partnerships include the EV Zug ice hockey club, the LK Zug handball team, the Securitas Team Schweiz (Swiss Tennis), Unihockey club Zug United, and football and swimming organisations in Baar. The hospital was also appointed main medical partner of Swiss Tennis from April 2024, a partnership running to the end of 2026, with Leemann as the designated official association doctor for that partnership.

Prior to his current role at Kantonsspital Zug, Leemann worked at GZO Spital Wetzikon in the canton of Zurich, where the sports medicine department under his involvement was certified as a Swiss Olympic-approved Sport Medical Base in December 2016. That certification, awarded by Swiss Olympic, recognised the institution’s commitment to supporting both elite and development athletes with integrated sports medical and physiotherapeutic care. Leemann was involved in the expansion and development of the sports medicine offering at GZO before moving to Kantonsspital Zug, where his current institutional role is more senior.

Swiss Tennis Team Doctor

Harald Leemann has served as team doctor to the Swiss Tennis national women’s team, the Securitas Team Schweiz competing in the Billie Jean King Cup (formerly the Fed Cup), for approximately eight years as of 2024. He was officially appointed association doctor of Swiss Tennis from 1 April 2024 under a contract extending to the end of 2026.

Swiss Tennis president Rene Stammbach confirmed Leemann’s appointment in a statement in 2024, describing him as having delivered excellent work as team doctor for eight years and noting his integral contribution to the team’s Billie Jean King Cup victory in 2022. The Swiss women’s team’s 2022 Billie Jean King Cup title was one of the most significant results in Swiss tennis history, and Leemann’s medical support across that campaign was part of his documented contribution to the team’s success.

The GZO Spital Wetzikon announcement from January 2017 confirms that Leemann attended the Swiss Fed Cup team as early as April 2016, placing the beginning of his Swiss Tennis team involvement before his meeting with Martina Hingis at the 2016 Rio Olympics that same year. His professional role with the national team was therefore the origin of his connection to Hingis, not a consequence of the relationship. The four players he was attending to in January 2017 at GZO were Timea Bacsinszky, Belinda Bencic, Viktorija Golubic, and Martina Hingis. His work with that group of elite players during one of the strongest periods in Swiss women’s tennis represents some of the most consequential sports medicine work of his career. The medical careers of practitioners at this level of elite sport are explored across recent profiles on the site.

Swiss Ski Freestyle National Team

Harald Leemann served as association doctor to the Swiss Ski Freestyle national team for over six years, a role he held before and alongside his involvement with Swiss Tennis. His profile describes him as an enthusiastic sportsman whose private sporting engagement is inseparable from his professional identity.

Swiss Ski Freestyle covers disciplines including moguls, aerials, ski cross, halfpipe, and slopestyle, all of which place extreme biomechanical demands on athletes and generate injury profiles that require specialist orthopaedic and sports medicine expertise. Serving as the national federation’s medical officer for over six years in that context represents a substantial commitment to a discipline with very different injury characteristics from tennis, demonstrating the breadth of Leemann’s sports medicine competence across high-impact winter sports and high-repetition racket sports simultaneously.

Marriage to Martina Hingis

Harald Leemann and Martina Hingis married on 20 July 2018 in Zug, Switzerland, in a private ceremony. Hingis was 37 and Leemann was approximately 38 at the time. Their meeting is traced to the 2016 Rio Olympics, where Hingis competed in women’s doubles with Timea Bacsinszky, winning the silver medal, and where Leemann attended as team doctor.

The wedding was reported by Swiss publication Blick and confirmed by Hingis through social media. The ceremony took place in Zug, where Leemann was professionally based and where the couple subsequently lived. On 9 March 2019, Hingis announced via Twitter the birth of their daughter Lia: “Harry and I are excited to welcome our baby girl Lia to the world. We are already so in love.” Lia was born in early March 2019.

Hingis spoke about her relationship with Leemann in interviews as one built on a genuine personal connection that developed from their professional proximity in the Swiss tennis world. His description by Swiss sources as a doctor from Zug, and her description of him as “Harry” in personal communications, reflects the informal familiarity of a long professional acquaintance before the romantic relationship developed.

In 2022, Hingis confirmed the separation in an interview with Blick, citing different visions of the future as the reason for the split. She said: “Yes, Harry and I have separated. We had different visions of the future.” Following the separation, Hingis and Lia moved from the family home in the canton of Zug into an apartment near her mother and her mother’s partner. Leemann has not made any public statement about the separation in any confirmed source. The separation was reported in August 2022. Leemann and Hingis have maintained a co-parenting arrangement for Lia.

His Former Wife: Martina Hingis

Martina Hingis, born 30 September 1980 in Kosice, Czechoslovakia (now Slovakia), is a Swiss professional tennis player who was ranked world number one in singles for a total of 209 weeks across her career and won five Grand Slam singles titles: the 1997, 1998, and 1999 Australian Opens, the 1997 Wimbledon Championships, and the 1997 US Open. She was inducted into the International Tennis Hall of Fame in 2013.

Hingis became the youngest Grand Slam singles champion in the Open Era when she won the 1997 Australian Open at the age of 16. Named by her mother after Martina Navratilova, she was trained from childhood by her mother Melanie Molitor, herself a former Czechoslovak professional player. Her distinctive tactical intelligence and court awareness produced a playing style that analysts and former players have consistently described as the most strategically sophisticated in women’s tennis of the late 1990s.

Hingis married Andrew Jarrett in 1999 but that marriage did not proceed. She married Thibault Hutin in 2010 and divorced in 2013. Her marriage to Leemann in 2018 was her second confirmed completed marriage. She retired from professional tennis for the final time in November 2017 after testing positive for cocaine at Wimbledon 2007, serving a two-year ban, returning in 2013, and then building an outstanding second career primarily in doubles. She won the 2016 Rio Olympics silver medal in doubles with Bacsinszky, which is the event through which she and Leemann met. She currently lives in Switzerland with Lia near her mother. Her personal life connects to profiles of people whose stories shaped Swiss and international sport.

Daughter Lia

Lia Leemann, the daughter of Harald Leemann and Martina Hingis, was born in March 2019 in Switzerland. She lives with her mother following the 2022 separation. Hingis has shared publicly that Lia has already tried her hand at tennis as a young child.

In an appearance on the Swiss podcast Lasser – Die Talkshow in March 2022, Hingis mentioned that her then three-year-old daughter had already tried tennis, a disclosure that generated considerable interest from tennis fans curious about whether the daughter of two tennis-connected parents would follow her mother’s path. Lia’s surname, Leemann, is her father’s. Hingis has shared limited photographs of Lia on her social media accounts, keeping her daughter’s image controlled while documenting family life in general terms. Lia is approximately seven years old as of 2026.

Net Worth and Professional Income

Harald Leemann’s net worth has not been publicly confirmed in any verified source. His income derives from his senior hospital role at Kantonsspital Zug, his national federation medical appointments, and any private practice income associated with those roles.

Senior hospital physicians in Switzerland at the deputy head level in a specialist department typically earn salaries in the range of CHF 200,000 to CHF 350,000 annually, reflecting Switzerland’s high professional remuneration standards. No public estimate of Leemann’s net worth exists in any reliable source, and the figures cited in some biographical profiles without sourcing should be treated as speculation.

Physical Appearance

Height and Body Stats

Harald Leemann’s physical measurements have not been formally documented in any public source. He is described in press photographs and public appearances as tall and physically active, consistent with his self-description as an enthusiastic sportsman.

Swiss institutional sources describe Leemann as an enthusiastic sportsman whose private sporting engagement is inseparable from his professional identity, a characterisation that places him within the tradition of Swiss sports medicine practitioners who are themselves active participants in the sports they serve.
