Peter is without a doubt the best improv teacher I ever had. I learned a lot and got to be part of a great community. The atmosphere of his workshops are very welcoming and judgement-free, I would recommend these workshops to anyone who's interested!

Ich hab mich am Anfang etwas gefürchtet. Reingestoßen und los geht’s. Aber WOW… was für eine tolle Erfahrung. Einen Haken hat das ganze natürlich: „wenn ich nur aufhören könnte“ Absolute Empfehlung, tolle Erfahrung, toller Lehrer!

Alexandra, Vienna

Peter is a great improviser and a wonderful teacher! Whether your new, advanced or have NO idea what improv is, take classes with Peter! He will make it easy, fun and you’ll leave the class with new friends and a greater understanding of improv.

Had an amazing time at my first improv class. 10/10 would recommend to any and all! I had never done any sort of improv or acting before and it was a great learning experience.

Right place to go if you are experienced in Improv acting but also if you are new to it! For me it was the first time and I loved it. No reason to be scared just go for it!
