About Ms Christella Antoni

I am a consultant Speech & Language Therapist, Senior Voice Specialist working with a wide variety of adult speech, voice and communication disorders. I work with both professional and non-professional voice users including performers and singing voice restoration.
I have over 20 years of experience working within the NHS including 15 years experience as lead clinician for Voice in 2 NHS trusts. I am an expert level practitioner in Transgender Voice modification and run the UK's leading private Voice service in this field.
I run training courses for SLTs in standard Voice and Transgender Voice.
My method of working involves targeting the specific therapy required for each client to maximise therapy outcomes.
Patient testimonial
"Christella was so reassuring when I was 100% aphonic for many, many weeks. She has also taught me techniques to help me use my voice effectively which I still use now months after my treatment. I can’t recommend Christella enough to anyone experiencing difficulty with their voice. As well as practically, she helped me enormously mentally when I was going through a very hard time after two vocal surgeries for cancer and couldn’t speak."
