Outwrite is the first sponsor to support the charity’s Great Gatsby-themed event, and is now calling on other local businesses to get involved.
The ball, which has a 1920s theme, takes place at St David’s Park Hotel, Ewloe, on Friday 6 November.
And with tickets selling fast, the PR agency is urging the region’s businesses to get behind the fundraiser.
Outwrite’s managing director Tracy North said: “The Wales Air Ambulance provides a vital service to the people across the country, and it relies solely on donations.
“Fundraising events are crucial to the charity’s operations, and we’re proud to be supporting its inaugural North Wales ball.
“I urge other businesses to book their tickets now and look at the sponsorship opportunities available to them to support this deserving cause.”
Wales Air Ambulance is an all-Wales charity providing vital emergency air cover for those who face life-threatening illness or injuries. It has carried out more than 22,000 missions to date since its launch on St David’s Day 2001.
From its airbases in Caernarfon, Swansea, and Welshpool, an air ambulance can be anywhere in Wales within 20 minutes of receiving an emergency call.
The charity needs to raise more than £6 million each year to keep the aircraft flying, and does not qualify for lottery or government funding.
Tickets are priced at £35 and include a drinks reception, three course meal and entertainment. To buy tickets to the event, which runs from 7pm til late, contact Debra on firstname.lastname@example.org or 0844 85 84 999.
