Professional tour^[2][3]

She began playing at the times of the hard rules of the communist period in Poland: tennis was considered by the authorities as a sport reserved for the elite and was not profitable because it was not among the Olympic sports then.

There were no financial possibilities to plan a professional career, no foundations for women professional tennis. Poland was facing economic catastrophe until the fall of communism.^[4]

At age 10, Katarzyna was encouraged to start playing tennis by her father Stanisław, a former soccer player of Start Łódź and a great sports enthusiast. Her mother Maria, an economist, was also very supportive of her.

At the beginning of her career, Katarzyna Nowak was coached by Maria Dowbor- Lewandowska and Wiesław Nowicki – a former Davis Cup player. As a girl, Katarzyna was showing a lot of strength, determination and full engagement. She quickly drew the attention of the Polish Tennis Federation and was hired on the national team at the age of 14.

She was a national champion in all age categories, winning two titles in 16-and-under competitions as well as four titles in 18-and-under.

As a junior, Katarzyna had difficulties traveling because of the political situation in Poland. At first, she could not obtain visas for the United States or Australia and after each tournament abroad, she had to return to Poland to get another visa. As a result, she could not play as many tournaments as her opponents, maybe half of what the others were doing. Each tournament was like an adventure. For instance, invited to the Jal Cup, she went alone to Tokyo where she reached the semi-finals. Or she arrived in Paris only on Sunday evening to play her first round of the French Open junior tournament on Monday.

She was already 18 years old, in her last junior year, when she had the opportunity to obtain all the necessary visas. In spite of all these difficulties, Katarzyna won eight titles and was runner up in 4 tournaments on the ITF Junior Tour. She won 18-and- under tournaments in Umag, Mexico, San Juan Puerto Rico, San Jose Costa Rica, Tashkent, Katowice, Nyiregyhaza and in Czechoslovakia.

She advanced to quarter-finals of the 18-and-under European Championships in Lisbon. In 1987 she was ranked 7th in the world ITF Junior ranking.

Due to the economic situation in Poland in the early 80s, Katarzyna was not able to combine her junior career with competition at the professional level which was the natural norm for other junior tennis players around the world.

She finally started her professional career in 1988. The beginnings were not easy as the economic crisis was at its peak with hyperinflation, non convertible currency and shortages of all kinds.

The subsequent years of her career coincided with the fall of communism and the transformation period that followed. In the early 90s, things started to slowly get better in Poland. But it all took time and came in slightly too late for Katarzyna who had already engaged on the professional tour... You could say she was born at least 10 years too early!

Possibilities to find better tennis training conditions – such as indoor courts – came too late for Katarzyna as well as the first major tournaments and opportunities for sponsorship deals. Deeply attached to her nation, Katarzyna Nowak never considered leaving Poland to seek better conditions in another country with a highly developed level of tennis. She played her whole career as a Polish player. Katarzyna showed her talent and an uncommon determination to become the first Polish women in Top 50 of the WTA rankings when she reached the WTA No. 47. She was leading the way to the next generation of Polish players, being an example for others starting their professional careers and a symbol for the future of professional tennis in Poland.

For all those reasons, her professional career should not be seen only from a statistical point of view as it would be an antihistorical approach. Katarzyna Nowak quite rightly deserves the status of a pioneer of Polish professional tennis. She well deserves this title as she was competing in an extremely unfavorable situation in the last years of communist rules and the early transition period.

She is also recognized as a symbol of the era of the Polish tennis breakthrough, which occurred following the fall of communism and the political transformation of the country from the Polish People's Republic to the Third Republic of Poland. Her results and success helped to create new professional tennis structures.

On the WTA Tour, her best performance was a semifinal appearance at the 1995 Barcelona Open.^[5] Soon after, she beat Kimberly Po and Meredith McGrath to make the third round of the 1995 French Open, then months later reached her career-high ranking of 47 in the world.^[6]

After winning three rounds of qualifications at French Open, she qualified to the second round in 1994 – losing to Lindsay Davenport, future world No. 1.
