Characters of Casualty - Jeff Collier

Jeff Collier played by Matt Bardock, is a Paramedic who first appeared on 10 February 2007.

He becomes good friends with Dixie, and when she is told budgetary constraints mean one of her team must be transferred, Jeff volunteers to go. He returns several months later, following the departure of Cyd Pyke. He discovers that fellow paramedic Snezana is stealing hospital equipment to help illegal Serbian immigrants, and reluctantly agrees to keep it a secret when she swears not to do it again. Jeff's wife leaves him and begins seeing another man. He sees his children infrequently, and offers Dixie his spare room when her house is burnt down. In November 2009, Jeff was struck on the back of the head by Alistair MacCormack, who believed that Polly (who he deludedly regarded as his "girlfriend") was seeing Jeff. Alistair also thought that Jeff had got a restraining order against him, but it was really Polly, who had reported Alistair to the police. Jeff was admitted to the ED. Dixie asks Jeff to marry her, to make her father proud. Her father is unaware that she is a lesbian but catches her kissing another woman and suffers a heart attack. During a call to a college shooting, Jeff witnesses the death of a student that leaves him suffering post-traumatic stress and threatened his job. He has since made a recovery.

In between part 1 and part 2 of the Holby Riots, Dixie & Jeff were in a red button special which sees Dixie encourage Jeff to speak to his children again.

Inside Soap described Jeff and Dixie as the 'dynamic duo'. In an interview with Inside Soap, producer Nikki Harris teased what was next for the two saying, "Dixie and Jeff were central to our opening episodes in Cardiff, as they really came under pressure with the car crash and the explosion that happened on the estate. And as we look at how the police interact with ED later on, the paramedics are going to be on the front line in terms of that, because they're sort of in between each side. So Jeff and Dixie are set to have key roles in those storylines when they play out on screen."
