Gérant Monsieur Coisnon
Jean-Claude Coisnon, son, grandson and great grandson of farmers, grew up in Méréville, in the Menesard farm.

In 1985, he graduated from the Beauvais Institut Supérieur Agricole, and as an agricultural engineer, worked for over ten years in the international cereal trade, as a trader.
In 1999, when he returned to the farm, he began cultivating potatoes, on twenty hectares.

In less than 10 years, the surface increased from 20 to 500 hectares and the tonnes produced from 1,000 tonnes to 30,000 tonnes.
Annual production is now 50,000 tonnes.
