After it was abandoned, it was bought in 1929 by the pastor Philadelphe Delord, who founded the Association for the Treatment of Victims of Tropical Diseases, and particularly for victims of leprosy. But since the treatments for leprosy became more and more effective, the Carthusian monastery needed a new vocation. It found one in 1975, when the Association decided to open a Center for Socio-Professional Reintegration and Readjustment. It was thus able to continue with its mission to give aid and support to people in difficult circumstances.
 
At present, the Carthusian Monastery of Valbonne has become a tourist site, offering tours of the monument, the forest, and its vineyard; it is also a place of residence, a cultural site, and a workplace.
