It is during 15 years working for one of the most prominent Parisian Atelier in France that Joseph Youss Kadri mastered his craft. Following an ancient tradition, he learned the art of restoration of antiques and gold gilding for years before being given the title of Master Gilder. He worked on the restoration of  prestigious buildings such as the "Versailles Castle", the "Dome des Invalides", the "Louvre Museum" among others. 

Since his arrival in the United States, Master Kadri has worked on private and public buildings. His portfolio includes indoor and outdoor projects from the West to the East coast.

He is Restorer/Gilder for the Carnegie Museum of Art of Pittsburgh and has been commissioned by the Carnegie Museum of Natural History of Pittsburgh. He is a founding member of the Western Pennsylvania Crafts Guild and is a member of the Society of Gilders in the USA.
