'Not many people know St John's Ambulance is the largest first-aid trainer in the country,' said Wright. 'Revenue from corporate training raises crucial funds, so we are keen to ensure people are aware of our offering.'
The charity is also aiming to recruit more volunteers by highlighting the number of events it attends. It currently has 3,000 volunteers in London.
'We provide support for more than 1,000 events in the capital every year, ranging from the London Marathon and the Lord Mayor's show to community events,' explained Wright.
Part of the campaign will highlight the charity's role as a back-up for the London Ambulance service, highlighting the support it provides in emergencies.
