Depth freediver · German national record holder · elite safety diver · ocean storyteller.
The career
Kathleen qualified for the German National Team in her very first competition — taking second overall in the women's ranking — and has represented Germany at the world championships since. She holds the German national record in constant weight no fins and competes across CWT, CNF and FIM.
What makes her rare is that she's elite on both sides of the line: as an athlete diving to 90 metres, and as a professional safety diver trusted at the sport's biggest events, including Vertical Blue and multiple world championships.
An instructor since 2020 and a natural storyteller, Kathleen shares the deep with a growing audience — in two languages, across social media, talks and press.
