Sonia trained at Laine Theatre Arts and upon graduating was immediately cast in the West End production of CATS at the New London Theatre where she made her professional debut as Gumbie Cat.

Sonia left the show to join the original West End cast of CHILDREN OF EDEN which was directed by John Caird and played at the Prince Edward Theatre. Following this she was part of the West End revival of JOSEPH AND THE AMAZING TECHNICOLOR DREAMCOAT at the London Palladium where she played the role of the Narrator on numerous occasions. After over two years in Joseph she was asked back to join the cast of CATS, but this time on the National Tour in the lead role of Grizabella.

Sonia returned to the West End as Gigi in the smash hit musical MISS SAIGON and can be heard performing the role on the Complete Symphonic Recording album of the show. Sonia then created the role of Mabel in the original London cast of FAME THE MUSICAL and can also be heard on the West End cast recording.

Between performing in the National Theatre and UK Tour production of OH! WHAT A LOVELY WAR, Sonia was cast in Cameron Mackintosh’s revival of OLIVER! which saw her return to the London Palladium. Cameron personally selected her to play the role of Nancy which she played to great acclaim. Following her successful stint in the West End production she was asked to recreate her role on the UK National Tour and at the Princess Theatre, Toronto. She can also be seen performing Nancy’s iconic song ‘As Long As He Needs Me’ in the filmed concert HEY, MR PRODUCER!
