About me

My swimming journey has taken me from Ängelholm through Helsingborg to Georgia Tech in the United States. Today I am pursuing the highest international level from Helsingborg while working part-time as a Data & Integration Specialist at NSVA. Curiosity and the drive to keep improving guide me, both in and out of the pool.

Speaking

An early talent. A late bloomer. The same drive.

I have been both an early and a late bloomer in swimming. In my talks, I share experiences of setting goals, managing expectations, and continuing to develop when progress is anything but straightforward. I have spoken for swimming clubs and federations and welcome enquiries from companies and sports clubs.

A big thank you to Daniel Kertes for an inspiring and engaging talk!

Daniel skilfully connected his experiences to both our club and the challenges our swimmers face in their everyday lives. By sharing successes as well as setbacks, he gave an honest picture of how development is rarely a straight path, but requires patience, hard work, and courage.

The talk inspired our swimmers to dare to set ambitious goals while offering valuable perspectives on handling pressure, setbacks, and uncertainty along the way. With warmth, humour, and great credibility, Danne created a moment that both moved and motivated the audience.

We are convinced that many of our swimmers left the talk with renewed energy, greater confidence, and a better understanding that both successes and setbacks are a natural part of the journey.

Thank you for a much-appreciated evening at ÄSS!

“Together, they gave a wonderful talk in Umeå during our forum in 2024. […] Two different, but very inspiring journeys to hear about!”

Together, they gave a wonderful talk in Umeå during our forum in 2024. We heard about their journeys up to the present day, what had mattered, and what had driven and motivated them! We also got to try some of their favourite exercises in the pool. Two different, but very inspiring journeys to hear about! ♥️

Let’s do something together.
