01 / About me
The player & person
I believe in steady improvement – with a clear plan, fun & intensity.
Professional on the WTA and ITF tour.
02Individual training for players of all levels.
03Experience and know-how for players, clubs and teams.
I started playing tennis at the age of six. My father, Michael, is a tennis coach, so the sport was close by from the very beginning – and what began as a game on the court became my path.
As a junior I trained at district, state association and national federation level and became German junior champion three times. International highlights included the European Championships, the Orange Bowl and the European Youth Olympic Festival (EYOF). After finishing school I decided to go all in and play the professional tour full-time.
Since 2018 I have lived the full tour experience, from ITF tournaments to WTA events. I won seven ITF titles and reached career-high rankings of 442 in singles and 401 in doubles. Unlike the top stars, I travelled most of the time without a coach by my side, so I took care of match analysis, opponent analysis, technique and tactics myself. I was also my own manager, handling scheduling, travel, budget and sponsors.
I ended my professional career at the WTA 250 in Iași in 2026. That year I tried a lot of new things: a short time at college at the University of Florida (UF), then training in Spain. There I saw how much earlier and more professionally you have to train to reach the top – and that, in my view, the structures in the federations are not professional enough to compete at the highest level.
I now know what it takes to get to the top, and I realised I had lost too much time on the way. That is why I decided to end my career. Now I want to give back to people who still have the chance to do things right.
