Samantha Dorrance has entered several dancing and singing competitions, including one for the BBC Television Programme, Blue Peter, which saw her get through to the semi-final live on BBC1. 
In 2007, Samantha won the High School Musical You're The Star! Competition on Disney Channel UK, after being voted by viewers. The prize for this was to have an all-expenses paid trip to London to record a music video. This video resulted in her appearing on her regional ITV news programme, Central Tonight. Her exceptional performance resulted in her being hand picked to audition for a role as presenter of the 2008 competition, My School Musical, which had a slightly different format. She was picked and presented the programme alongside Brad Kavanagh.
In September 2009, Samantha successfully auditioned for the part of Wendy in the pantomime Peter Pan which was performed at the brand new Theatre Severn in Shrewsbury, Shropshire from December 2009 into January 2010. She performed alongside Emmerdale star Matt Healy who played Mr Darling and Captain Hook.
She took on the lead role of Cinderella at The Theatre Severn in Shrewsbury from December 2010 to January 2011.
Between February and April 2011 Sam played the part of Tracey in a brand new play by Alan Share called Death of A Nightingale at The New End Theatre in Hampstead, London and from June 2011 until March 2012 will be touring the UK and Ireland in the hit musical Dreamboats and Petticoats playing the lead role of Laura.
