When was Dominic Thiem born?

Dominic Thiem was born on September 3, 1993 in Wiener Neustadt, Austria.

Where does he come from?

Thiem is Austrian. He grew up in Lichtenwörth, a small Austrian town of 2,727 inhabitants (as of January 2018). He still lives there. He joined Austrian military service from November 2014 to April 2015.

What languages does he speak?

Thiem is fluent in German and in English (he is a Chelsea fan in football). He also learned how to speak French during his relationship with France’s Kristina Mladenovic.

How tall is Dominic Thiem?

Thiem’s height is 6’1” (185cm), according to his profile on ATP official website. His weight is 174lbs (79kgs), by the tour’s official measures.

Who is Dominic Thiem’s girlfriend?

Kristina Mladenovic and Thiem were in a relationship for about two years. The Austrian made it official during the ATP Nitto Finals in 2017 in London, where the French tennis player sat in Thiem’s box during all his matches. The couple then went public about their love on social media. But they split up towards the end of 2019. Thiem talked about their breakup in February 2020, during a press conference. “Being in a relationship implies commitment, time and focus. For now, I am not looking for a partner, even if I am not closing any doors. I am sure that in the future, you will see a girl in my box to cheer me up.”

Who is Dominic Thiem’s coach?

Thiem has been coached by Chile’s Nicolas Massu since February 2019, whilst his father Wolfgang remained part of his staff. Massu, a former ATP world No.9 and a 2004 Olympic singles champion in Athens, replaced Günter Bresnik. Bresnik officially  began his collaboration with Thiem in 2002, even though they had known each other since 1997, when Thiem’s parents came to Vienna to work in Bresnik’s international tennis academy. Bresnik also coached Boris Becker, Henri Leconte, Patrick McEnroe and Ernests Gulbis. A former coach of the Austrian Davis Cup team and Austrian tennis Federation director, he is known for his unusual methods. Spain’s Galo Blanco was part of Thiem’s staff during the 2018 season.

In January 2020, Thiem announced he had committed to a 20-week collaboration with Thomas Muster, the 1995 French Open winner and only world No. 1 in Austria’s history, who would work as an adviser for Thiem. Muster also was the captain of the Austrian team during the 2020 ATP Cup. But the pair split just two weeks after Thiem’s announcement.

“We ended our working relationship, explained Thiem at the time. It did not fit. It’s easy like that. It is just about work. We get along well personally and we said in the beginning. If anything is not all right, we will tell each other.”

His fitness coach is Duglas Cordero and his physiotherapist is Alex Stober.

Who is his father?

Wolfgang Thiem is a tennis coach. He works as a coach for fellow Austrians Dennis Novak and Sebastian Ofner on tour. He is also part of his son’s team and has followed him to tournaments, alongside Nicolas Massu, since the second half of the 2019 season. Dominic Thiem’s mother, Karin, is also a tennis coach. She started a tradition after his 2019 Indian Wells title by getting a tattoo each time her son wins a trophy. His brother Moritz, born in 1999, is a pro tennis player, but hasn’t reached the top 1000 yet.

When did Dominic Thiem turn pro?

Thiem, who idolized fellow Austrians Stefan Koubek and Jurgen Melzer, was a junior star. He was the world No.2 in the ITF ranking (singles and doubles combined) in January 2011. He was a runner-up at the 2011 French Open Boys’ tournament (lost in the final against Bjorn Fratangelo). He then won the Orange Bowl, one of the five “Grade A” tournaments on the junior tour. Thiem started his pro career that same year, receiving wildcards at Kitzbühel, Bangkok and Vienna. Fittingly, he claimed his first professional win in Vienna against then 44-year-old Austrian legend Thomas Muster.

Thiem’s career is managed by Herwig Straka, from the Emotion Group. The agency is under contract with other personalities from tennis (Tommy Haas, Thomas Muster, Anastasija Sevastova) and from sports in general (Thomas Vanek, Mirna Jukic…). It also organizes ATP tournaments in Stuttgart, Vienna and Mallorca, as well as the WTA event in Berlin.

What is Dominic Thiem’s net worth?

Thiem earned about 23 million dollars (20 million pounds) from prize money in tournaments. He has also endorsements from sponsoring contacts with Adidas (clothing), Babolat (racquet), Bank of Austria, Rolex and Kia.
