Prior to her election, Turner was a doctor in the Springburn area in Glasgow, Scotland for 25 years. Before that, she was an anesthetist for ten years. She was lured to seek political office due to the cut in services at Stobhill hospital. Turner also campaigned against Labour's treatment of the NHS. Because of this, she stood as a candidate in the Strathkelvin and Bearsden Holyrood By-Election of 2001. In that race, she got 7,572 votes or 18%. In 2003, she stood again in Strathkelvin and Bearsden on the same platform she used in 2001. This time, Turner won the seat with 10,988 votes or 31%. This win prompted the loser, Labour MSP Brian Fitzpatrick, to remark:
"Narrow win, big win, whatever, it is still a disappointment, but we are coming back for this seat." [1]
