Chalk first joined London’s Air Ambulance as an advanced trauma paramedic in 1997 and subsequently served the longest secondment in the history of the service.

In 2004, Chalk returned in a different role, becoming London Ambulance Service Clinical Liaison Officer, working as lead paramedic and point of contact between the London’s Air Ambulance charity and the ambulance service.

Chalk has personally selected, trained and mentored all paramedics who served with London’s Air Ambulance since 2004. In 2019, he won the Highly Commended Award from the Chairman of the Association of Air Ambulances for his dedicated career with the service.

On receiving the award, Chalk said: “It is an honor to be receiving a Highly Commended award from the Chairman of the Association of Air Ambulances. I first joined London’s Air Ambulance on secondment in 1997 and it has been a privilege to have achieved so much with them over these years. These awards are particularly meaningful as the recognition is from peers who understand the challenges of the industry.”
