People will be able to learn life-saving skills as part of an open evening hosted by Bicester St John Ambulance.
Visitors will also get the chance to meet members, look around its new Crusader ambulance, and find out more about what the branch does.
The branch decided to organise the event after its success at Bicester Carnival last month.
Sarah Orgill, divisional superintendent, said: "The number of inquiries we received at the carnival was well above our expectations. Many people wanted to know more.
"The open evening will allow us to explain our work and the courses we offer the public."
The event takes place tomorrow at the branch headquarters, in Ashdene Road, from 7.30pm to 9.30pm.
There will also be a competition to win a free place on a life-saver babies and children course.
