Iain Dean (born 1983/1984) is a paramedic for the Holby Ambulance Service. He joined the service in August 2013 as a student paramedic and remained in that position until April 2014 when he left to go travelling. He rejoined in October that year following Jeff's death, after becoming a fully qualified paramedic.
In August 2016, just after the events of the helicopter crash at the ED, Iain and Jez were paired up with F1 Jasmine Burrows as a part of her training. During their shift, they were called out to the scene of an accident where Morven was volunteering at a homeless kitchen. Iain and Jez later joined Morven and Jasmine for drinks at a club after their shift.
Michael Stevenson currently portrays Iain on Casualty as a series regular, and has been a part of the main cast since its 28th series. He made a guest appearance as the character on Holby City in August 2016 alongside Lloyd Everitt who portrays Jez Andrews.
