Resonance Voice Training is a company based in London. It is led by founder Louise Kerr and its excellence depends on a select team of hand picked associates.
We have all had careers as professional performers having sung and acted across the UK and Europe. We all have experience and excellent track records in teaching and training communication skills.
Working across the UK we offer a range of courses for educational and public sector establishments, for charities, corporate sector companies and individuals.
Our highly adaptive approach can be tailored to meet most needs. In the last year, for example, we have tailored courses for newly qualified teachers, civil servants, corporate executives, chambers, doctors, social workers, call centres, and university academics.
We have also taught young people involved in the theatre and public speaking and others in need of interview skills.
