About me
[metaslider id=“706″]
„Do it with passion or not at all!“
Sports, especially swimming, accompanies me for over 20 years.
After 17 years of competitive swimming at state level I began my journey outside the pool as project and social media manager at Swim Performance and schwimmtrainer.de – brands of the ATX-Training GmbH.
Since 2017 I am managing Marco Koch, the European and World Champion. Since 2021 I am working with World Record holder Andrii Govorov on building up a personal brand.
I am looking forward to supporting you with my experiences on your way to the top!
In 1999 I started swimming in a club. 10 years later I began to take over tasks within the executive board as well as on the pool deck as a coach. Until 2021 I was member of the executive board in a swim club.
