Now a familiar face on BBC Breakfast's sofa, Sian Williams spent more than a decade in radio news before trying her hand at television presenting.
Sian began her career in radio before going on screen
Hailing from Eastbourne in East Sussex, Sian gained a BA in English and History at Oxford Polytechnic before studying critical journalistic writing at Rhode Island University in the USA.
She shared her family's enthusiasm for news and soon embarked on her journalistic career with BBC Radio Merseyside as a trainee reporter in 1986.
Over the next five years Sian reported from Liverpool, Manchester, Sheffield and Leeds before moving to national radio.
She started out as a producer on BBC Radio 4's news and current affairs programmes but was quickly promoted to output editor, responsible for the editorial content of programmes.
She took responsibility for programmes on major news events and followed Bill Clinton during his 1992 US presidential campaign and produced live programmes on the IRA ceasefire.
She also secured exclusive interviews with many of the major players involved with the Bosnian peace accord, including the subsequently indicted war criminal Radovan Karadzic.
After more than a decade in radio, Sian's break into television came when she accepted a job as an assistant editor on News 24, the BBC's continuous news channel.
Her break into television presenting however followed a more unusual path.
During a day of screen testing for prospective presenters, one fell ill and Sian was asked if she would like to have a go.
She did, and was so successful she was offered the 4 till 7pm slot co-presenting with Gavin Esler.
After more than two-years with the channel, Sian became a special correspondent with the Six O'Clock news before joining BBC Breakfast as a presenter.
She is married with two children and lives in north London.
