Adam Chesters, Aircrew Doctor
I grew up on the Wirral and spent most of my spare time playing football and golf before going to medical school at the University of Leicester (where I played even more football!). Since graduating, I have worked in Oxford, the Isle of Man and Sheffield before moving to Cambridge in 2006. I specialised in Emergency Medicine and have additional qualifications in Sport and Exercise Medicine.
I wanted to be a HEMS doctor following a visit to London’s Air Ambulance in 1999 and now feel proud and privileged to be working with a dynamic team of doctors, paramedics and pilots in Essex and Herts. It is a thrill to be part of such a professional crew that brings life-saving interventions to seriously injured people. I have been utterly astounded by the tireless work of the charity and volunteer staff who promote the cause and rally the donations in order to keep the aircraft flying.

Paula Johnson, Aircrew Paramedic
As well as flying with the Herts Air Ambulance, I work as a Duty Operations Manager in the Letchworth Locality. I have been a Paramedic for 18 years and prior to that I was an ITU nurse.
Mike Yeldham, Aircrew Paramedic
I have been in the Ambulance Service for the past 10 years starting off in the patient transport service. Eighteen months later I progressed to emergency ambulances at Letchworth ambulance station and am now flying with the Air Ambulance. Before joining the Ambulance Service I worked as a wood machinist.
Chris Martin, Aircrew Paramedic
When I am not flying with the Air Ambulance I am an Emergency Care Practitioner in Welwyn Garden City and have been qualified as a Paramedic for 6 years. Prior to joining the Ambulance Service I worked as a Lifeguard whilst studying for a Diploma in Sports Science. I currently live in Hitchin, Herts.
David Kerr-Sheppard, Pilot
I work for Medical Aviation Services (MAS), the company responsible for supplying the Herts Air Ambulance. I was in the RAF for over 30 years and spent most of my time flying the RAF’s Search and Rescue Sea King helicopters. I graduated from the Central Flying School as a Qualified Helicopter Instructor and spent 4 years instructing on the Sea King. I retired from the RAF in 2008 and enjoy flying the Herts Air Ambulance.
I enjoy photography, eating out and I am an England Netball qualified umpire.
