Jeffrey "Jeff" Collier (October/November 1971 - 4 October 2014) was a paramedic in the Holby Ambulance Service. He joined the service in 2007 and worked alongside his close friend, and later wife Kathleen "Dixie" Dixon during his time with the service. He worked with the service for over seven years, until his sudden death in October 2014 in a vehicle explosion.

Early life

Jeff was born to Billy Collier, and was one of three children, the others being Richard and Margaret. At some point prior to joining the ambulance service, Jeff met Lucy, who he later married.

Dixie and Jeff on their wedding day.

In February 2010, Dixie was shocked when her father, Arthur, arrived and told her he didn't have long to live. He jumped to conclusions that Dixie was in a relationship with Jeff when he saw them together, not knowing that she was a lesbian. He was delighted by the relationship, so Dixie didn't tell him the truth. He continued to mistake Jeff and Dixie for a couple, and told Dixie how anxious he was to see her get settled before he died. This lead Dixie to give her dad what he wanted, so she proposed to Jeff and they married.

Jeff was a football-supporting geezer, but he was also a fantastic paramedic. He hated ‘Broken Britain’ and so he often took the youth of today under his wing, and he tried to make them the best that they can be. He pretended to be the King of his castle, but secretly he knew that Dixie wears the trousers. He had authority on the street and that's priceless to his colleagues. While climbing out of an overturned minibus in a RTA, the bus exploded and killed Jeff. (CAS: "Born Lucky") His funeral took place the following week. (CAS: "The Last Call")

Personal life

Prior to being a paramedic, Jeff was married to Lucy Collier and they had two children; John and Sophia. After the two divorced, Jeff married co-worker Kathleen Dixon in 2010 to cover up her homosexuality from her father.

In 2014, Jeff began a relationship with Tamzin Bayle, another paramedic who worked for the ambulance service. Despite being married to Dixie at the time, he said to her that he would have to get a divorce if he were to continue his relationship with Tamzin. However, before anything could come of it he perished when a vehicle exploded which had crashed earlier with some ED staff inside. (CAS: "Born Lucky")
