Cocal Leadership & Public Speaker

Your voice says a lot about you to your colleagues.

I help you to explore and identify the effective use of your voice communication, everything that goes beyond words. 

Your leadership, charisma, congruence and overall impact are analysed and optimised.


Questions about the different possibilities of individual consultations and prices?


More recently, I have been invited to present my work at prestigious schools such as the Manhattan School of Music. I also collaborate with many members of the medical profession to apply my concepts to pathological cases.

Finally, 2015 saw the culmination of a long-term project with the publication of the book “The Path of the Voice” published by Favre. That same year, the Breathing Coordination training I gave myself was extended to the USA with a first course in Los Angeles. Since 2012, several vocal consulting mandates have taken place as well as interventions and conferences, for example:

  • San-Francisco (“Julia Nielsen vocal studio”)
  • Geneva (“Formation continue de la confédération des écoles de musique genevoise”, “Les musiciens de l’Atelier”)
  • Liverpool ( Liverpool institue of performing arts, Balance vocal studio )
  • London (“Shedlight events”)
  • Los Angeles ( Elizabeth Prescott
  • Voice Studio & Vocalize you winter retreat )
  • Slovenia (Master class)

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.

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 singers, 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. The multiple trainings I have followed and my pedagogical sense allow me to be a quality asset for politicians, business leaders, or managers who want to ensure the vocal health of their artists, for the artists themselves, who are guided and reassured about their possible problems, and for anyone who wants to optimize the use of their voice for any type of communication.
