My mission is to help people and companies enter into dialogue through the effective use of voice, language, and body language to achieve optimal communication and increased well-being in human relationships.

I achieve this through the following means

  • diagnosing inefficient and unconscious voice and breathing habits
  • developing the full use of the vocal function
  • strengthening the awareness of the breathing mechanism
  • applying breathing and vocal functions to the structure of language

My vision is to become a leader in vocal excellence, enabling high profile people to reach their audience, and transforming the way they perceive their communication to those around them.

  • A passion shared worldwide
  • A love of challenge
  • Listening to needs
  • Trust & Respect
  • Open communication
  • Excellence & Success
  • Breathing Coordination
  • Laryngeal coordination
  • Phonetics and prosody
  • Body language assessment
  • Awareness and functional analysis
  • Breathing Mechanics in Communication
  • Comparative analysis of audiovisual material
  • Individual sessions
  • Group sessions

Vocal Leadership & Public Speaking

Vocal consulting is the provision to the subject of various skills allowing a balanced and healthy vocal gesture. The vocal consultant balances the respiratory system, the vocal cords and the emotions linked to the vocal act. He is trained to recognise and decipher the various vocal symptoms.

He proposes solutions to solve the difficulties encountered by comedians, artists, business leaders, politicians, public speakers and lecturers. A significant part of vocal consulting is experienced in individual lessons due to the personal and individual nature of the balancing that is involved.

On this basis, I work as a voice consultant in Switzerland and internationally.
