Her varied and extensive practice includes working with classical actors, international film stars, artists in national theatre companies, leads in West End musicals, actors in film and television and platinum selling pop artists.

She acts as a vocal consultant to West End production companies as well as individuals, working as a trouble-shooter and problem solver in both speaking and singing.
She is also one of the most experienced teachers and trainers of the Estill Model in the world and was trained by and interned for Jo Estill. She was the first UK teacher to be asked by Estill to intern for her in Denmark in 1994 and she continued her close association with her from that time. She has pioneered the use of the Estill Model in the teaching of actors, and specialises in the integration of speaking with singing, especially musical theatre.

This was followed in 2005 with a production of Art by Yasmina Reza and Into the Woods by Stephen Sondheim for the Royal Academy of Music. In 2008 she directed Sondheim’s Company, and in 2010 A Little Night Music also for the Royal Academy of Music.
