Kelly is an actress, musical performer and choreographer. She has understudied and played Tanya in Mamma Mia at the Prince of Wales and Prince Edward Theatre, understudied Nikki and Ursula in the award winning production of Sweet Charity at the Crucible Theatre, and other roles / credits in productions for Cameron Mackintosh - Hey Mr Producer, Encore Mr Producer, Jean Ann Ryan Productions - Smokey Joe's Café, and NCL productions - 42nd Street, Pirates of Penzance.
Kelly was a mentor for the ACG Mentoring Programme 2007-08, and writes: "As a Christian working in the theatre, I have often been hesitant in telling a brother or sister in Christ what my work is, partly because of the stigma that goes along with an artist in the theatre. To have a venue like the ACG Mentoring day to express your concerns as an artist and as a Christian makes the burden of the industry a little less heavy. Not only do you meet fellow Christians that understand fully your feelings and issues but a network of prayer that can help you through your career."
