About me

Hi, I'm Katrin Targo,
"the 3-headed Dragon":
Opera Singer, Mental Hygienist & Online Entrepreneur

Most of my life I have been a musician – an opera and classical singer. Since 2018 I added Mental Hygiene to my “bag of tricks” – and have been growing my online studio and teaching about successful online business creation since 2020. 

What my students say

My career has taken off like crazy after I finished the Win the Mental Game for Singers Online Course! I loved every minute of it and showed up for myself. I did all the exercises and am now enjoying emotional freedom and a better self esteem. Thank you, Katrin!

Win the Mental Game for Singers
I feel so much happier and more relaxed in my life. I have the tools to make my life better by choosing better thoughts day by day. It was very hard for me in the beginning.. but the longer I kept to the principles of meditation and mental hygiene, the easier it became. I love my life now and allow myself to enjoy my life again.

Meditation Starter Kit
When I started my singing studies with Katrin Targo, I had created my own way of singing since childhood.. My method was not usable within the classical world.
Katrin helped me to understand the world of sounds more clear and after only about 10 lessons I could keep to the correct pitches and singing has since then become a great pleasure! I am so happy to have the technique now to sing also the more difficult pieces!
