About me


Individual and personal advice is the focus of my work.

It is important to me that my patients, big or small, enjoy learning. In addition to jointly planning the therapy goals, I rely on my professional knowledge from various advanced training courses. 

The aim of my work is to provide you with practical knowledge so that you learn to deal with your challenges independently.​

My practice is officially recognized by the Austrian professional association as a teaching practice for students of the speech therapy course. I am also an NF!T® therapist and have received the CPD+ (Continuing Professional Development PLUS) certificate.

I am looking forward to meet you!
