"I can only warmly recommend Ms. Keller. She was a valued marketing colleague for many years with extraordinary know-how in online and offline marketing (strategic as well as operational).
Her other passion, breathing therapy, inspired me and gave me back my grounding and inner peace during a stressful time."

"The breathing work is wonderful & gives me time once a week to clear my head, start the day stress-free, invigorated & highly focused. Kirstin's calm & level-headed manner plays a particularly important role for me here. Thank you for your great work Kirstin!"

"Kirstin offered PME right at the beginning of the corona phase and it was a complete success! Her calming manner and the effective structure of the exercises quickly got me out of the hectic pace of everyday life. Practicing the right breathing technique also helps me to collect myself and stay focused in my normal working life. The tension in my neck and shoulders was relieved surprisingly quickly and if you attend the course regularly, you learn a lot of techniques that you can also put into practice on your own. Kirstin responds to all the needs of the participants and thus increases the chances of success in improving the muscles and relaxation."

"The breathing exercises have had a huge impact and have helped me to regain a clear head and balance even in the most stressful moments. After the breathing exercises with the right technique, I really notice how my productivity increases thanks to greater concentration and the right focus. Thank you very much, Kirstin!"
