Lisa Vennart

I started my career with the London Ambulance Service in 2003 as an Emergency Medical Technician and qualified as a Paramedic in 2007. Since then, I’ve been lucky enough to work in a variety of roles across the LAS, each giving me new experiences and challenges along the way. In 2016, I qualified as a Clinical Team Manager, a role that allowed me to support colleagues and help shape the care we deliver on the front line.
