Operation Smile is an international medical charity specialising in cleft surgery and care for babies, children and adults. Since 1982, the organisation has transformed lives through safe surgery and comprehensive cleft care, while strengthening local health systems through training, education and partnerships Operating in more than 30 countries, Operation Smile raises around $100m globally each year. Operation Smile UK plays a vital role within this international network as a fundraising office, working closely with Operation Smile Inc. to fund programmes and support medical volunteers delivering care around the world.
